Draw a quadrilateral that is not a rectangle. describe your shape, and explain why it is not a rectangle.

One example of a quadrilateral that is not a rectangle is a rhombus, the shape of a diamond
The reason we know it's a quadrilateral is because we can count out it's four sides. We know it is not a rectangle since rectangles should have four right angles, but a rhombus has two acute and two obtuse angles. That means it is not a rectangle! 

Hope this helped! :)
