4/8 What are the characteristics of a parallelogram? A parallelogram has two pairs of parallel sides. Opposite sides are equal. Opposite angles are equal. Any two consecutive angles add up to 180 degrees. The area of a parallelogram = base x height. (Kaplan's SAT in a Box)
4/7 CORROBORATE. (ku rah bu rayt). verb. to support with evidence. "Unless you can corroborate your story, it will not be admissible in court," the attorney told his client. Synonyms: verify, prove. (Kaplan's SAT in a Box)
4/6 CONDUIT. kahn doo ut). noun. means for transmitting or distributing. Jason, a notorious gossip, was a conduit for information about his friends. Synonyms: channel, pipeline. (Kaplan's SAT in a Box)
3/20 What are the characteristics of a rectangle? A rectangle is a four-sided figure with four right angles. Opposite sides are equal. Diagonals are equal. The perimeter of a rectangle is equal to the sum of the lengths of the four sides, which is equivalent to 2(length + width). The area of rectangle = length x width. The perimeter of a 7-by-3 rectangle is 2(7 +3) = 20. The area of a 7-by-3 rectangle is 7 x 3 = 21.
3/19 What are scalene, isosceles, and equilateral triangles? Scalene triangles are triangles in which no sides, and no angles, are equal. Isosceles triangles are triangles that have two equal sides. Not only are two sides equal, but the angles opposite the equal sides, called base angles, are also equal. Equilateral triangles are triangles in which all three sides are equal. Since all the sides are equal, all the angles are also equal. All three angles in an equilateral triangle measure 60, regardless of the lengths of sides. (Kaplan's SAT in a Box)
3/18 CORRECTIVE. (ku rehk tihv). adjective. intended to correct. The school decided to take corrective measures to prevent truancy. Synonyms: remedial, curative. (Kaplan's SAT in a Box)
3/17 COMPREHENSIBLE. (kahm prih hehn su bul). adjective. Understandable. Shannon spoke slowly so her directions would be comprehensible to her foreign visitor. Synonyms: intelligible, coherent. (Kaplans' SAT in a Box)
3/16 COMPULSION. (kum pul shun). noun. an irresistible impulse. Tamar, a shoe fanatic, could not resist the compulsion to buy the shiny red boots. Synonyms: urge, obligation. (Kaplan's SAT in a Box)
3/13 What is the Triangle Inequality Theorem? The length of one side of a triangle must be greater than the difference and less than the sum of the lengths of the other two sides. For example, if it is given that the length of one side is 3 and the length of another side is 7, then you know that the length of the third side must be greater than 7 - 3 = 4 and less than 7 + 3 = 10.
3/12 How do you find the area of a triangle? The area of a triangle = 1/2 (base)(height). The height is the perpendicular distance between the side that's chosen as the base and the opposite vertex.

3/9 COMPOSED. (kum pohzd). adjective. calm. Although her stomach was in knots, the actress appeared perfectly composed when she took the stage. Synonyms: serene, unperturbed. (Kaplan's SAT in a Box)
3/6 If given an equation of a line, how do you find its y-intercept? To find the y-intercept, you can either put the equation into y= mx +b (slope-intercept) form--in which case "b" is the y-intercept--or you can just plug x = 0 into the equation and solve for" y". For example, in the equation y +3x -5, -5 is the y-intercept by both methods. The point where the line crosses the y-axis is (0,-5). Also, to find the x-intercept, plug y = 0 into the equation and solve for x. For example, in the equation y - 3x - 5, substituting y = 0 into the equation: 0 + 3x - 5. 5 = 3x. 5/3 = x
3/5 If given an equation of a line, how do you find its slope? To find the slope of a line from an equation, put the equation in to the slope-intercept form: y = mx + b. The slope is "m". For example, to find the slope of the equation 3x + 2y = 4, rearrange it: 3x + 2y = 4. 2y = -3x +4. y = -3x/2 + 2. The slope is -3/2.
3/4 COMBATIVE. (kum ba tihv). adjective. eager to fight. he teacher suggested that the combative student channel his aggression into boxing. Synonyms: aggressive, belligerent. (Kaplan's SAT in a Box)
3/3 COMBUSTION. (kum bus chun). noun. act of burning. Campers must use fire with great caution to prevent combustion of the parched brush. Synonyms. igniting, kindling. (Kaplan's SAT in a Box)
2/27 What is a function and how do you evaluate one? Standard function notation is written f(x) and read "f of x". To evaluate the function f(x) = 2x + 3 for f(4), replace every x with 4 and simplify: f(4) = 2(4) + 3 = 11.
2/26 How do you solve an inequality? To solve an inequality, do whatever is necessary to both sides to isolate the variable. Just remember that when you multiply or divide both sides by a negative number, you must reverse the inequality symbol. For example, to solve -5x + 7 <-3, subtract
2/25 COMMEMORATE. (ku meh mu rayt). verb. to mark with a ceremony. Each year, the Franklins commemorate their anniversary by visiting the site of their first date. Synonyms: observe, remember. (Kaplan's SAT in a Box)

2/23 CLARITY. (klehr u tee). noun. clearness. The refreshing water in the mountain stream was remarkable for its clarity. Synonyms: lucidity, limpidity. (Kaplan's SAT in a Box)
2/13 How do you solve a system of equations? You can solve for two variables only if you have two distinct equations. Two forms of the same equation will not be adequate. Combine the equations so that one of the variables cancels out. For example, to solve the two equations 4x + 3y = 8 and x + y = 3, multiply both sides of the second equation by -3 to get: -3x - 3y = -9. Now, add the two equations. The 3y and the -3y cancel out, leaving; x + -1. Plug that back into either one of the original equations and you'll find that y = 4. (Kaplan's SAT in a Box)
2/12 How do you translate English expressions into algebraic expressions? Systematically turn phrases into algebraic expressions and sentences into equations. Be careful about order, especially when a problem calls for subtraction. For Example: The charge for a phone call is "r" cents for 3 minutes and "s" cents for each minute thereafter. What is the cost, in cents, of a phone call lasting exactly "t" minutes? The charge begins with "r", and then something more is added, depending on the length of the call. The amount added is "s" times the number of minutes past 3 minutes. If the total number of minutes is "t", then the number of minutes past 3 is t - 3. So the charge is r + s(t - 3). (Kaplan's SAT in a Box)
2/11 CLARITY. (klehr u tee). noun. clearness. The refreshing water in the mountain stream was remarkable for its clarity. Synonyms: lucidity, limpidity. (Kaplan's SAT in a Box)

2/6 What does solving "in terms of" mean? To solve an equation for one variable in terms of another means to isolate the one variable on one side of the equation, leaving an expression containing the other variable on the other side of the equation. For example, to solve the equation 3x - 10y = -5x + 6y for x in terms of y, isolate x: 3x - 10y = -5x + 6y. 3x + 5x = 6y + 10y. 8x = 16y. x = 2y. (Kaplan's SAT in a Box)
2/5 How do you solve a linear equation? Do whatever is necessary to both sides to isolate the variable. For example, to solve the equation 5x - 12 = -2x + 9, first get all the x's on one side by adding 2x to both sides: 7x - 12 = 9. Then, add 12 to both sides: 7x = 21. Then, divide both sides by 7: x = 3. (Kaplan's SAT in a Box)
2/4 COMBUSTION. (kum bus chun). noun. act of burning. Campers must use fire with great caution to prevent combustion of the parched brush. Synonyms: igniting, kindling. (Kaplan's SAT in a Box)

1/30 How do you add and subtract monomials? To ad or subtract monomials, first make sure that the terms to be combined have exactly the same variables. This makes them "like terms". Then, to combine like terms, keep the variable part unchanged while adding or subtracting the coefficients. For example: 2a + 3a = (2 + 3)a = 5a (Kaplan's SAT in a Box)
1/29 How do you determine the absolute value of a number? The absolute value of a number is the distance of the number from zero on the number line. Because absolute value is a distance, it is always positive. The absolute value of 7 is 7; this is expressed |7| = 7. Similarly, the absolute value of -7 is 7:|-7| = 7. Every positive number is the absolute value of two numbers: itself and its opposite. (Kaplan's SAT in a Box)
1/28 COMPOSED. (kum pohzd). adjective. calm. Although her stomach was in knots, the actress appeared perfectly composed when she took the stage. Synonyms: serene, unperturbed. (Kaplan's SAT in a Box).

1/23 How do you count the total number of possibilities for several events to occur? The fundamental counting principle: If there are "m" ways one event can happen and "n" ways a second event can happen, then there are "m X n" ways for the 2 events to happen. For example, with 5 shirts and 7 pairs of pants to choose from, you can have 5 x 7 = 35 different outfits. (Kaplan's SAT in a Box).
1/22 COMPULSION. (kum pul shun) . noun. an irresistible impulse. Tamar, a shoe fanatic, could not resist the compulsion to buy the shiny red boots. Synonyms: urge. obligation. (Kaplan's SAT in a Box)

1/20 How do you find the mode of a set of numbers? The mode of a set of numbers is the value that appears most often. For example, if your test scores were 88, 57, 68, 85, 99, 93, 93, 84, and 81, the mode of the scores would be 93 because it appears more often than any other score. If there is a tie for the most common value in a set, the set has more than one mode.
1/16 How do you find the mode of a set of numbers? The mode of a set of numbers is the value that appears most often. For example, if your test scores were 88, 57, 68, 85, 99, 93, 93, 84, and 81, the mode of the scores would be 93 because it appears more often than any other score. If there is a tie for the most common value in a set, the set has more than one mode.
1/15 How do you find the median of a set of numbers? The median of a set of numbers is the value that falls in the middle of the set.

12/12 How do you find the missing number in a series when you are given the average? To find the missing number when you're given the average, use the sum. For example, if the average of 4 numbers is 7, then the sum of those 4 numbers is 4 x 7 or 28. Suppose that 3 of the numbers are 3, 5 and 8. These 3 numbers add up to 16 of that 28, which leaves 12 for the 4th number. (Kaplan's SAT in a Box)
12/11 If you have an average of a series of numbers, how can you find their sum? Sum = Average x Number of Terms. If the average of 10 numbers is 50, then they add up to 10 x 50 or 500. (Kaplan's SAT in a Box)
