## Classifying Quadrilaterals

A

**quadrilateral**is a shape with four straight sides. There are many types of quadrilaterals, and they are classified based on their diagonals, the number of parallel sides, and congruent angles.## Trapezium

- One pair of opposite sides are parallel

## Kite

- Two pairs of adjacent sides are equal
- One pair of opposite angles are equal
- Diagonals intersect at right angles

## Parallelogram

- Opposite sides are equal
- Opposite sides are parallel
- Opposite angles are equal
- Diagonals bisect each other

## Rhombus

- All sides are equal
- Opposite sides are parallel
- Opposite angles are equal
- Diagonals bisect each other at right angles
- Diagonals bisect the angles of the rhombus

## Rectangle

- Opposite sides are equal
- Opposite sides are parallel
- All angles are 90°
- Diagonals are equal
- Diagonals bisect each other

## Square

- All sides are equal
- All angles are 90°
- Opposite sides are parallel
- Diagonals are equal
- Diagonals bisect each other at right angles

The classifications of quadrilaterals should be review for you, but feel free to use this page as a reference as well as your text book.
