Challenge Level

The picture above shows an equilateral triangle, with lines drawn between various midpoints.

Have a go at printing out this triangle, and cutting along the lines to make nine smaller shapes.

If the area of the smallest equilateral triangle is one unit, what is the area of each of the other shapes?

We can take a collection of the smaller cut out areas and rearrange them to make different shapes.

Using the nine smaller shapes:

**How many different trapezia (which are not parallelograms) can you make?****How many different parallelograms (which are not rectangles) can you make?****How many different rectangles can you make?****Which other quadrilaterals can you make?**
