A quadrilateral is any closed four-sided figure. There are two types of quadrilaterals: concave and convex. A concave quadrilateral has a part that goes into the shape, while a convex quadrilateral has angles all on the outside corners of the shape. Let’s look at all of the different properties of every kinds of convex quadrilaterals.

Sometimes you’ll need to draw in the height once you determine which sides are the parallel bases.
