And one way to define concave quadrilaterals-- so let me draw it a little bit bigger, so this right over here is a concave quadrilateral-- is that it has an interior angle that is larger than 180 degrees. So for example, this interior angle right over here is larger than 180 degrees. And it's an interesting proof. Maybe I'll do a video.

So a square is a special kind of rectangle, it is one where all the sides have the same length. Thus every square is a rectangle because it is a quadrilateral with all four angles right angles. However not every rectangle is a square, to be a square its sides must have the same length. 12 comments.Proving Quadrilaterals Given the four coordinates, draw a diagram of your quadrilateral.
