Congruent acute or obtuse angles








This picture is of a regualr building that has a very intresting outside. The outside of the building forms two congruent acute angles. You can tell that they are congruent by the curve in each drawing.

I found this picture on: http://math8geometry.wikispaces.com/constructing_a_triangle_with_a_compass
