What is a quadrilateral?

Category: Mathematics


A quadrilateral is defined as any two-dimensional, four-sided shape that has four vertices with interior angles that equal 360 degrees. There are several quadrilateral variations that include parallelograms, rectangles, rhombuses, squares, trapezoids, and kites.


  • Parallelogram – A parallelogram consists of two pairs of parallel sides. Opposite angles are equal. Rectangles, rhombuses, and squares are also considered parallelograms.
  • Rectangle – A rectangle has four sides; each side is a right angle (90°).
  • Rhombus – A rhombus has four sides, each one being of equal length and parallel to the opposite side. A rhombus with all right angles is a square.
  • Square – A square has four equal sides and four equal angles (90°).
  • Kite – A kite is a quadrilateral with two pairs of equal length, adjacent sides.
  • Trapezoid – A trapezoid is a quadrilateral that consists of 2 parallel sides.
