Parallelograms

THINGS TO DO

You should have two acute Isotiles.

Arrange these two Isotiles to make a parallelogram.

In the new shape you have made, you should be able to see that the opposite sides are equal. Can you see that they are parallel too?

Add up all the angles so that you know their sum. Is this the same answer as you got for the trapezium?
