###
ADJACENT ANGLES

Angles that have a common vertex and a common side.

###
ALTERNATE EXTERIOR ANGLES

A pair of angles on the outer sides if two lines cut by a transversal, but on opposite sides of the transversal.

###
ALTERNATE INTERIOR ANGLES

A pair of angles on the inner sides of two lines cut by a transversal, but on the opposite sides of the transveral.

###
COMPLEMENTARY ANGLES

two angles whose measures have a sum of 90 degrees

###
CORRESPONDING ANGLES

Angles that are on the same side of the transversal and are both above or both below the lines cut by the transversal.

###
D=rt

distance = rate x time

###
FUNCTION FAMILIES

A function is an input- output relationship that has exactly one output for each input.

###
HYPOTENUSE

the side opposite the right angle in a right triangle

###
INFINITE

never-ending; going on forever

###
LEGS OF A TRIANGLE

the two sides that are not the hypotenuse.

###
LINE OF BEST FIT (CONCEPTUAL)

A straight line that best fits the data on a scatter plot. It can be used to predict a trend in the data.

###
MONOMIAL

an expression that is a number, a variable, or a product of numbers and/or variables

###
NONLINEAR EQUATION

An equation or inequality that, when represented graphically, results in a graph that is not a straight line (eg, circle, parabola, hyperbola).

###
PERFECT SQUARE

The product when a whole number is multiplied by itself.

###
PYTHAGOREAN THEOREM

In a right triangle, the sum of the squares of the length of the legs is equal to the square of the length of the hypotenuse., a²+b²=c²

###
QUADRATIC EQUATIONS

a function in the form: f(x) = ax² + bx + c = 0, a≠0.

###
SEQUENCE

the order in which things happen

###
SLOPE INTERCEPT FORM

an equation written in the form y=mx+b is in slope-intercept form. The graph is a line with slope m and y-intercept b.

###
SUPPLEMENTARY ANGLES

Two angles whose sum is 180 degrees

###
TRANSVERSAL

a line that intersects two or more lines at different points.

###
VERTICAL ANGLES

A pair of opposite congruent angles formed by intersecting lines.

###
VERTICAL LINE TEST

A test used to determine whether a relation is a function by checking if a vertical line touches 2 or more points on the graph of a relation
