WebStep 2: Determine the ratio. Since two angles are equal, the triangle is an isosceles right angle triangle and hence two sides will be equal. Therefore let sides a = k, b = k. Thus we have, by the converse of Pythagoras theorem. c = a 2 + b 2 = k 2 + k 2 = 2 k 2 c = 2 k. The ratio of a: b: c is 1 k: 1 k: 2 k o r 1: 1: 2.
