Quadrilateral. A quadrilateral is a polygon that has exactly four sides. (This also
means that a quadrilateral has exactly four vertices, and exactly four angles.) ...
A quadrilateral is a four-sided polygon with four angles. There are many kinds of
quadrilaterals. The five most common types are the parallelogram, the rectangle
(If the points do not lie in a plane, the quadrilateral is called a skew quadrilateral.)
There are three topological types of quadrilaterals (Wenninger 1983, p.
A quadrilateral is any four sided figure. Do not assume any additional properties
for a quadrilateral unless you are given additional information.
Classification of Quadrilaterals. Quadrilateral is a geometric shape that consists
of four points (vertices) sequentially joined by straight line segments (sides).
