Quadrilateral literally means four sides. Any shape that has four sides will be considered a quadrilateral. The name itself is a coinage of quad and lateral. Quad means four and lateral is side. A quadrilateral is a two dimensional figure.
A quadrilateral is a polygon in Euclidean plane geometry with four edges (sides) and four vertices (corners). Other names for quadrilateral include quadrangle (in analogy to triangle ), tetragon (in analogy to pentagon, 5-sided polygon, and hexagon, 6-sided polygon), and 4-gon (in analogy to k -gons for arbitrary values of k ).
A quadrilateral is a polygon that has exactly four sides . (This also means that a quadrilateral has exactly four vertices, and exactly four angles.) Some examples of quadrilaterals: Discussions of 2-D shapes sometimes refer only to the boundary (the line segments that form the edges of the figure) or to the interior as well.
Quadrilateral Definition. A quadrilateral is a plane figure that has four sides or edges, and also have four corners or vertices. Quadrilaterals will typically be of standard shapes with four sides like rectangle, square, trapezoid, and kite or irregular and uncharacterized as shown below: Types of Quadrilaterals. There are many types of quadrilaterals.
