Why is quadrilateral important? The properties and rules governing the geometric shapes known as quadrilaterals are used to create floor plans for new buildings or to create buildings or spaces through engineering and architecture. In its simplest definition, a quadrilateral is a geometrical form with four sides. Examples could be table top, book, picture frame, door, baseball diamond etc. Since these shapes are so common, quadrilaterals are also used in graphic art, sculpture, logos, packaging, computer programming and web design; in fact, there are few areas of daily life where there are no examples of quadrilaterals. In geometry, a quadrilateral can be defined as a closed, two-dimensional shape which has four straight sides. The polygon has four vertices or corners. We can find the shape of quadrilaterals in various things around us, like in a chess board, a deck of cards, a kite, a tub of popcorn, a sign board and in an arrow.
