What is a quadrilateral?

Answer: A quadrilateral is defined as any twodimensional, foursided 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.
Quadrilaterals
 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.
