Kepler triangle Kepler triangle A Kepler triangle is a right triangle with edge lengths in a geometric progression in which the common ratio is , where is the golden ratio, and can be written: formula_1, or approximately 1 : 1.272 : 1.618. The squares of the edges of this triangle are in geometric progression according to the golden ratio. Triangles with such ratios are named after the German mathematician and astronomer Johannes Kepler (1571–1630), who first demonstrated that this triangle is characterised by a ratio between its short side and hypotenuse equal to the golden ratio. Kepler triangles combine two key mathematical
