 Acute Angle pg 70 An Angle that has a degree measure between 0 and 90. Acute Triangle pg 70 A triangle with three acute angles. Addition Property of Equality pg 44 Adding the same member to each side of an equation results in a equivalent equation. Adjacent Angles pg 64 Angles that have a common side, the same vertex, and do not overlap. alternate exterior angles pg 66 When a transversal intersects two lines and on opposite sides of the transversal. 1 2 3 4 5 6 7 8 Alternate interior Angles pg 66 When a transversal intersects two parallel lines, the angles between the two lines and on opposite sides of the transversal. 1 2 3 4 5 6 7 8 Altitude of a Triangle pg 89 A line segment from a vertex and perpendicular to the opposite side. Angle pg 70 Two rays with a common endpoint. DEF = DEF Arithmetic Sequence pg 3 A list of numbers where consecutive numbers have the same difference. Associative Properties pg 10 The way in which addends or factors are grouped does not changed the answer. Average pg 150 Adding the numbers together, and dividing the sum by the addends. base (of an exponent) pg 4 The number that is used as a factor in a power. In the base is 4. bisect pg 78 To separate a figure into two congruent parts. box and whisker plot pg 156 A way to organize numerical data to show the median, quartile, and interquartile range. Circle pg 89 A plane figure formed by all points that are the same distance from a given point in the plane called the center. Circumcenter pg 89 The intersection of the three perpendicular bisectors of the sides of a triangle. It is used to draw a circumscribed circle around a triangle. Common Factor pg 94 A whole number that is a factor of two or more given whole numbers. 3 is a common factor of 6 and 9. Common Multiple pg 96 A whole number that is multiple of two or more givine whole numbers. 36 is a common multiple of 6 and 9. Commutative Properties pg 10 The order in which numbers are added or multiplied does not change the answer. 8 + 5 = 5 + 8 2 x 30 = 30 x 2 Complementary angles pg 64 Two angles are complementary of the sum of their degree measures is 90. Congruent Figures pg 68 Figures that have the same size and shape. Constructions pg 78 Drawings made with a straighedge and a compass. Correlation pg 160 Relationship between two variables. Corresponding angles pg 66 When a transversal intersects two parallel lines, the angles in similar positions. 1 2 3 4 5 6 7 8 Cube Root pg 6 One of three equal factors of a number. 2 is the cube root of 8 since 2 x 2 x 2 = 8 Data pg 148 Numerical information Decimal (Decimal fraction) pg 104 A way of expressing factions that have denominators of 10,100, 1000 and so on. Degree pg 64 A common unit of measure for angles. Diagonal pg 70 A line segment from one vertex of a polygon to any nonadjacent vertex.
