Since this triangle is similar to the original triangle, we can set up the equation We can figure out that this triangle has a base of length □ − 1, while the legs are of length 1. This splits the triangle into two new isosceles triangles, one of which is a 72-72-36 triangle. Then we draw the bisector to one of the 72° angles. We let the base of this isosceles triangle have length 1, and the legs have length □. The two angles you mention, □∕5 = 36° and □∕10 = 18°, we can actually find exact expressions for that aren't too complicated.
