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
