What 2 figures Will

have 20 edges?

Convex, cyclic, equilateral, isogonal, isotoxal. In geometry, an icosagon or 20-gon is a twenty-sided polygon. The sum of any icosagon interior angles is 3240 degrees.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
