Question from Ellie:

is a rectangle a parallelogram?

Hi Ellie,

In our Glossary of Mathematical Terms we define a parallelogram as a quadrilateral with both pairs of opposite sides parallel.

Is a rectangle a quadrilateral?

Does a rectangle have both pairs of opposite sides parallel?

If the answer to both these questions is yes then it is a parallelogram.
