Pythagoras' theorem with other polygons

If the squares on the sides of a right-angled triangle are replaced by other regular polygons, does the sum of the areas of the two smaller polygons equal the area of the largest polygon? This investigation provides great practice on using the sine rule for the area of a triangle (although can also be done without!) and calculating the area of any regular polygon.
