As shown in the figure below, ABCDEFGH is a regular octagon. Prove
that the area of the red shaded region is equal to the area of the yellow
shaded region.

A conformal mapping or conformal transformation is a continuous mapping preserving the form of infinitesimal figures. This conformal map produces a realistic view of the original image or map. This the conformal transformation of problem1430.
