Topics on Pedal Polygons

General Mathematics 2021-08-20 v1

Abstract

In this paper, we study several topics on pedal polygons. First, we prove the existence for pedal centers of triangles in a new way. From its proof, we find that the sum of area of outer and inner polygons is invariant under rotation. Finally, we investigate when a polygon will be a pedal polygon of another one.
