Perimeter | the measure of the distance around a figure |
percent of change | the difference of the new and original divided by the original |
absolute value | the distance of a number from zero on a number line |
acute angle | an angle that measures less than 90 degrees |
Supplementary angles | the sum of two angles that equals 180 degrees |
adjacent angles | angles that have a common vertex and a common side. Angles that next to each other. |
volume | the number of cubic units needed to fill a given space |
Independent Variable | is the input to a function and is normally denoted by the symbol x |
Dependent Variable | The output number of a function and is normally denoted by the symbol y. |
Scientific Notation | a method of writing very large, or very small numbers by using powers of 10 |
Domain | the set of all possible input values of a function |
Range | the set of all possible output values of a function |
Inverse operations | Operations that undo each other |
transformation | a change in the size or position of a figure |
Vertical Angles | A pair of opposite congruent angles formed by intersection lines |
Independent Outcome | An event whose outcome has nothing to do with the outcome of other event(s). |
Dependent Outcome | An event whose outcome is affected by the outcome of another event(s). |
Rational Numbers | any number that can be expressed as a ratio of two integers. |
Integers | Set of whole numbers and their opposites. |
Whole numbers | Natural numbers and including zero |
Natural numbers | The set of numbers used for counting that consists of all the positive numbers, excluding zero. |
Irrational numbers | A number that cannot be expressed as a fraction. |
equation | A mathematical statement that represents the equality of two expressions involving either constants, variable(s), or both. |
inequality | A relationship between two expressions that are not equal, often written with the symbols >, >, <, and < |
expression | A mathematical phrase that contains operations, numbers, and/or variables |
Commutative Property | property that states that the order does not matter when adding or multiplying. |
Associative Property | property that states that the grouping does not matter when adding or multiplying |
Correlation | A relation between two variables that vary together. If one variable always increases as the other increases, the relationship is said to be positive or direct. Otherwise, the relationship is negative or inverse. |
surface Area | The area of the outer surface of a three-dimensional object. |
Dilation | A transformation that enlarges or reduces a figure. |
Translation | a movement (slide) of figure along a straight line |
Rotation | A transformation in which a figure is turned around a point |
Pythagorean theorem | A theorem stating that in a right triangle the area of the square on the hypotenuse is equal to the sum of the areas of the squares drawn on the other two legs. |
