Classifying Quadrilaterals

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

A parallelogram has opposite sides that are equal in length, opposite angles that are equal, and the diagonals bisect each other.

A rhombus has all sides of equal length, while a rectangle has opposite sides that are equal and all angles are right angles.

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

An isosceles trapezoid is a trapezoid with non-parallel sides that are equal in length.

A square is a quadrilateral with all sides equal in length and all angles equal to 90 degrees.

It can be classified as a parallelogram, rectangle, rhombus, or square.

All squares are rhombuses, but not all rhombuses are squares. A square has right angles, while a rhombus does not.

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

Yes, a trapezoid can have right angles, making it a right trapezoid.
