A quadrilateral is a four-sided polygon. There are several types of quadrilaterals, each with its own unique properties.

Square: A square is a quadrilateral with four equal sides and four right angles. All four sides of a square are congruent (have the same length).

Rectangle: A rectangle is a quadrilateral with four right angles and opposite sides that are equal in length.

Rhombus: A rhombus is a quadrilateral with four sides of equal length, but the angles are not necessarily right angles.

Parallelogram: A parallelogram is a quadrilateral with opposite sides that are parallel and equal in length. The opposite angles of a parallelogram are also equal.

Kite: A kite is a quadrilateral with two pairs of adjacent sides that are equal in length. The diagonals of a kite intersect at a right angle.

Trapezoid: A trapezoid is a quadrilateral with two sides that are parallel and two sides that are not parallel. The non-parallel sides are called the “legs” of the trapezoid. The distance between the parallel sides is called the “height” of the trapezoid.

Each type of quadrilateral has its own specific properties, and it is important to understand these properties in order to classify and work with quadrilaterals.
