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

CORRESPONDING ANGLES

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
