# Math Infographic, Geometry Problem 1335: the Lune of Hippocrates has the same area of a Kite. Mobile Apps. Level: College, High School.

 The figure shows a square ABCD inscribed in a circle O. S is the area of the right triangle AOB, S1 is the area of the lune of Hippocrates bounded by the semi-circle of diameter AB and the arc AB. A radius OE extended cuts semi-circle AB at F. S2 is the area of the kite EHFG (H on OA extended, G on OB extended). S3 and S4 are the areas of the triangles EFH and EFG, respectively. S5 and S6 are the areas of the curved triangles AFE and BFE.Prove that (1) S3 = S5; (2) S4 = S6; (3) S = S1 = S2; (4) AB2 = 4.AH.BG.This entry contributed by Markus Heisss, Wurzburg, Bavaria.
