Distance Formula

SUPPLEMENTARY

two angles are supplementary angles when adding their measure of degree equals 180.

COMPLEMENTARY

two angles are complimentary when adding their measure of degree together equals 90.

Angle Measures

• The sum of the angle measure of a quadrilateral is 360º.

• w + x + y + z = 360º

Quadrilaterals Defined

• A polygon with 4 sides

• All sides are straight

Parallelogram properties

• opposite sides are parallel (2 pairs)

• diagonals bisect each other

• diagonals are not congruent

Parallelogram Properties
