TermDefinition
Area the number of square units needed to cover a surface or figure
Circumference the distance around a circle
Vertex the point where two sides intersect
Complementary Angles the sum of two angles equal 90 degrees
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.
