In the figure below, prove that the area of
a right triangle ACB of altitude CH is equal to the sum of the areas
of the lunes A1, A2, A3, and A4.
Hippocrates of Chios (c.470 BC 
c.410 BC) was a Greek mathematician who worked on the classical
problems of squaring the circle and duplicating the cube.
Squaring the circle or the
quadrature of the circle is one of the three great
problems of Classical Geometry. It is the challenge to construct
a square with the same area as a given circle by using only a
finite number of steps with compass and straightedge.
