What Are Quadrilaterals A Quadrilateral is a closed figure WITH FOUR SIDES. The inner angles of the quadrilateral add up to 360 degree. The EXTERIOR ANGLES of a quadrilateral also add up to 360 degrees.
Types Of Quadrilaterals Square Rhombus Kite Rectangle Parallelogram Trapezium
PARALLELOGRAM Diagonally opposite angles are equal. Opposite sides are of equal length. Opposite sides are parallel. The diagonals bisect each other.
RECTANGLE All angles are equal (90°). Opposite sides are of equal length. The diagonals are equal in length.
RHOMBUS Diagonally opposite angles are equal. All sides are of equal lengths. Opposite sides are parallel. The diagonals bisect each other at 90°.
SQUARE A square is a regular quadrilateral. All angles are equal (90°). All sides are of equal length. Opposite sides are parallel. The diagonals bisect each other at 90°. The diagonals are equal in length
KITE Two pairs of sides are of equal length. One pair of diagonally opposite angles is equal. Only one diagonal is bisected by the other. The diagonals cross at 90°.
TRAPEZIUM One pair of opposite sides is parallel.
