 location in space point geometric figure which has no size point flat surface with no thickness plane series of points which extends in oppposite directions without end line part of a line with two endpoints segment or line segment part of a line with one endpoint ray are in the same plane but never intersect parallel lines share one common point intersecting lines do not lie in the same plane skew lines two rays with a common endpoint angle formed by two intersecting lines, are opposite and equal to each other vertical angles angles with the same measure congruent angles angles whose sum of their measures is 180 degrees supplementary angles angles whose sum of their measures is 90 degress complementary angles angle whose measure is 180 degrees straight angle angle whose measure is 90 degrees right angle angle whose measure is greater than 90 degrees obtuse angle angle whose measure is less than 90 degrees acute angle line that intersects two other lines in different points transversal angles which lie on the same side of the transversal in corresponding positions corresponding angles angles which are between two parallel lines and on opposite sides of the transversal alternate interior angles closed plane figure with at least three sides polygon triangle with three angles less than 90 degrees each acute triangle triangle with one angle measureing 90 degrees right triangle triangle with one angle greater than 90 degrees obtuse triangle triangle with three unequal sides scalene triangle triangle with two equal sides isosceles triangle triangle with three equal sides equilateral triangle most general name for a four-sided figure quadrilateral four-sided figure with both pairs of opposite sides parallel parallelogram most general name for a polygon with four angles each equal to 90 degrees rectangle polygon with four equal sides and four angles equal to 90 degrees square four-side figure with exactly one pair of parallel sides trapezoid polygon with four congruent sides but not four congruent angles rhombus five-sided polygon pentagon six-sided polygon hexagon figures with the same size and shape; corresponding parts have equal measures congruent figures Rule which states that, if three sides of two triangles are congruent, the two triangles are congruent Side-Side-Side Rule which states that, if two sides and the included angle of two triangles are congruent, the two triangles are congruent Side-Angle-Side Rule which states that, if two angles and the included side of two triangles are congruent, the two triangles are congruent Angle-Side-Angle the name for the distance around a circle circumference the formula for the distance around a circle C = 2(pi)r or C - pi)d segment which has one endpoint at the center of a circle and the other endpoint on the circle radius chord which passes through the center of a circle diameter segment whose endpoints are on the circle chord comparison of two quantities by division ration ration which compares quantities in different units rate rate with a denominator of 1 unit rate an equality of two ratios proportion figures with the same shape but not necessarily the same size similar enlarged or reduced drawing that is similar to an actual object or place scale drawing possible results of an action outcomes any outcome or group of outcomes sampel space (number of favorable outcomes)/ (number of possible outcomes) probability opposite of an event complement (number of favorable outcomes)/ (number of unfavorable outcomes) odds in favor (number of unfavorable outcomes)/ (number of favorable outcomes) odds against ratio that compares a number to 100 percent an amount based on how much an employee sells commission (amount of change) x 100/ (original amount) percent change amount of increase of an item which is profit mark-up amount of a price decrease of an item discount integers which differ by 1 consecutive initial amount of money deposited or invested principal amount of money earned on an investment interest percent which determines the amount of interest interest rate interest paid only on the principal simple interest interest paid on the principal and the acuumulated interest compound interest principal plus the interest balance set of ordered pairs relation first coordinates in a relation domain second coordinates in a relation range a relation in which each member of the domain is paried with exactly one member of the range function test in which you use a vertical line to determine if a relation is a function vertical line test an ordered pair that makes an equation in two variables true solution any equation whose graph is a line linear equation ratio which describes the tilt of a line slope point wher a line crosses the y-axis y-intercept y = mx + b slope-intercept form of an equation writing a function using f(x) instead of y function notation equation which describes a function function rule graph which shows the relationship between two sets of data scatter plot two or more equations system of equations line which borders the graph of a linear inequality boundary line number of square units enclosed by a figure area line segment perpendicular to the linen containing a base of the figure and drawn from the side opposite that figure height three dimensional figure space figure has two parallel bases that are congruent polygons and lateral faces that are parallelograms prism has a base that is a polygon pyramid has two parallel bases that are circles cylinder has one circular base and one vertex cone set of all points in space that are a given distance from a given point called the center sphere pattern you can form into a space figure net sum of the areas of the bases and lateral faces of a space figure surface area sume of the areas of lateral faces lateral area tilted space figure oblique space figure whose lateral faces are perpendicular to its bases right sliding a figure vertically and/or horizontally translation new figure after a transformation image type of symmetry in which a congruent figure is formed by rotating the orginal rotational symmetery line which divides a figure into two congruent figures line of symmetry type of transformation in which a figure is "flipped" over a line reflection transformation in which a figure is turned about a fixed point rotation
