Properties of Quadrilaterals

A quadrilateral is a polygon with four sides, four vertices, and four angles.

In a parallelogram, opposite sides are equal in length, opposite angles are equal, and the diagonals bisect each other.

A rhombus is a type of parallelogram where all four sides are of equal length.

A rectangle has opposite sides equal and all angles are right angles, while a square has all sides equal and all angles are right angles.

A trapezoid is a quadrilateral with at least one pair of parallel sides.

The sum of the interior angles of a quadrilateral is 360 degrees.

A kite is a quadrilateral with two distinct pairs of adjacent sides that are equal.

A square can be identified by having all sides equal and all angles measuring 90 degrees.

The diagonals of a rhombus bisect each other at right angles.

A convex quadrilateral is a quadrilateral where all interior angles are less than 180 degrees.
