 Adjacent (angle relationship) Angles immediately next to each other Alternate exterior angle Alternate exterior angles are on opposite sides of the transversal, but outside the parallel lines Alternate interior angle Alternate interior angles are two congruent interior angles that lie on different parallel lines and on opposite sides of a transversal. complementary Two angles whose sum is 90 degrees corresponding Corresponding angles are angles that are in the same position; they are made by lines cutting through two or more other lines Cost per unit Unit rate; A unit rate compares a quantity to its unit of measure. dilation Dilation is a similarity transformation in which a figure is enlarged or reduced using a scale factor , without altering the center. Distance formula (d=rt) The length between two points (or objects) Distributive property (algebraic) Multiplying a number is the same as multiplying its addends by the number, then adding the products A product can be written as, the sum of, or difference between, two products Experimental probability Experimental probability of an event is the ratio of the number of times the event occurs to the total number of trials. exterior The angle formed outside a polygon when one side is extended infinite Unable to be counted, unlimited; opposite to finite intercept In mathematics, an intercept is the coordinate of the point at which a curve intersects an axis. For example, an x-intercept or a y-intercept. interior An angle within two lines when they are crossed by a third line Line of best fit (conceptual) A line of best fit is a straight line that best represents the data on a scatter plot. This line may pass through some of the points, none of the points, or all of the points. Nonlinear equation Containing a variable with an exponent other than one. Used of an equation. Perfect square an integer which is the square of some other integer, i.e. can be written in the form n2 for some integer n (and because of this a square is always nonnegative). Thus a perfect square always has a square root that has no decimal expansion. an algebraic expression that can be factored as the square of some other expression, e.g. a2 ± 2ab + b2 = (a ± b)2 Pythagorean theorem The area of the square built upon the hypotenuse of a right-angled triangle is equal to the sum of the areas of the squares upon the remaining sides Scientific notation A way of writing very large or very small numbers using a number between 1 and 10 multiplied by a power of ten sequences An ordered set of numbers, shapes, or other mathematical objects, arranged according to a rule Slope intercept form Slope-intercept form is when a line is in the form y = mx + b where m is the slope and b is the y-intercept. Square root A number when multiplied by itself gives the original number supplementary Two angles whose sum is 180 degrees Theoretical probability Theoretical Probability of an event is the number of ways that the event can occur, divided by the total number of outcomes. Vertical angles Pair of angles directly opposite each other, formed by the intersection of straight lines Vertical line test Vertical Line Test is a test to determine if a relation or its graph is a function or not. For a relation or graph to be a function, it can have at most a single y-value for each x-value. Thus, a vertical line drawn at any x-position on the graph of a function will intersect the graph at most once.
