# 勾股定理离散性质的推广和应用—Pythagorean方程和特殊的M角数An Extension of Pythagorean Equation with Its Application—Pythagorean Equation and Special M-Gonal Numbers

Abstract: Based on the solution of Pythagorean Equation, we obtain a relationship that the difference be-tween two M-Gonal numbers is still an M-Gonal number. With this explicit computable expression, we establish a remarkable connection between two pairs of numbers. The projected planes of two pairs of numbers generate partial topological structure. In real Desarguesian projective plane, this structure shares many existing properties of topological ellipsoid naturally.
