Quadrilaterals – Definition, Types, Properties & Examples
Quadrilaterals are among the most fundamental shapes in geometry. Though simple in appearance, they form the basis of countless mathematical ideas and appear constantly in real life, from floor tiles and windows to playing cards and kites.

Quadrilateral -- from Wolfram MathWorld
A quadrilateral, sometimes also known as a tetragon or quadrangle (Johnson 1929, p. 61) is a four-sided polygon. If not explicitly stated, all four polygon vertices are generally taken to lie in a plane. (If the points do not lie in a plane, the quadrilateral is called a skew quadrilateral.)

Properties of Quadrilaterals - learnmath.org
A quadrilateral is any polygon with exactly four sides, four vertices, and four interior angles. Quadrilaterals are everywhere — windows, doors, floor tiles, tabletops, picture frames, and roof trusses.
