A quadrilateral is a closed figure with four straight sides. A closed figure means there are no gaps between sides and no side extends past the end of another side. If both segments lie inside the quadrilateral, then the figure is convex.
The origin of the word quadrilateral is the two Latin words quadri, a variant of four, and latus, meaning side. Quadrilaterals are simple (not self-intersecting) or complex (self-intersecting), also called crossed. Simple quadrilaterals are either convex or concave.
