Free Classroom Poster: Quadrilaterals

Here is another great math poster to decorate your classroom.  Today's poster is about quadrilaterals and illustrates the six major quadrilateral shapes.

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,

Anyhow, there are some facts on quadrilaterals, you can download this great poster here.
