Identifying 2d shapes

This week we have been learning about 2d shapes that we or maybe you didn't know of.
First, we learnt what a quadrilateral is a four sided shape and that vertices= corners.
Then we learnt what a trapezoid and a rhombus is, a trapezoid is a four sided shape that has two sides facing the same direction and the other two are going across, and the rhombus is a four sided shape that all sides are the same length.
