Free Classroom Poster: Quadrilaterals

Quadrilateral just means "four sides" (quad means four, lateral means side).  Any four-sided shape is a Quadrilateral.   The sides have to be straight, and it has to be 2-dimensional.

Quadrilaterals are simple (not self-intersecting) or complex (self-intersecting), also called crossed. Simple quadrilaterals are either convex or concave.

The interior angles of a simple quadrilateral ABCD all add up to 360 degrees of arc,
