A golden triangle is an obtuse isosceles triangle in which the two shorter sides have equal lengths and in which the ratio of this length to that of the third, bigger side is the golden ratio. The angle formed between the the smaller sides is equal to 108 degrees and the other two angles formed are 36 degrees each. It can be found in the pentagram as well as in the pentagon.
