What is a quadrilateral? Simply It just means four sides. (quad means four, lateral means sides) It has four sides, four vertices, and the interior angle sum adds up to 360.

## SQUARE

A square has congruent sides and all four angles are right angles, 90 degress; this makes it equilateral and equiangular. Because of its definition, every square is also a rectangle, rhombus, and a parallelogram.

## RECTANGLE

A rectangle has four right angles as well. It also has opposite sides that are parallel and congruent.

## PARALLELOGRAM

A parallelogram has opposite sides that are parallel and congruent in length. Opposite angles are congruent also.

## RHOMBUS

A rhombus has 4 congruent sides. All opposite sides are parallel and opposite angles are equal in length. Every rhombus is a parallelogram.

## TRAPEZOID

A trapezoid has exactly one pair of parallel sides. The parallel sides are called he bases and the other sides are called the legs.

## ISOSCELES TRAPEZOID

An isosceles trapezoid has congruent legs and parallel bases.

## KITE

A kite has two pairs of congruent adjacent sides. The angles are equal where the pairs meet.
