Hippocrates of Chios made some achievements with lunes on route to seeing if they could square the circle

maybe tell students that the semicircles have a side of a triangle as a diameter
maybe wait for them to ask
maybe they will assume that this is the case anyway...

following on from areas of circles (and Pythagoras' theorem) you can set your students two problems that are almost 2500 years old
