Tom Woodward/CC-BY-2.0 By its very definition, a quadrilateral is merely a shape with four sides and four vertices or corners. By its very definition, a quadrilateral is merely a shape with four sides and four vertices or corners. (This also means that a quadrilateral has exactly four vertices, and exactly four angles.) Learn the term quadrilateral as well as trapezoid, parallelogram, rectangle, rhombus, and square. In many quadrilaterals all the sides are of different lengths and all the angles are of different sizes. Hence, it is a quadrilateral. This is a special case of the n-gon interior angle sum formula: (n − 2) × 180°. Each point where two sides touch is called a vertex. Name an odd number greater than ten. (b) A square is a quadrilateral with four congruent sides.
