Webr1=2r2=3r3 Then r1/6=r2/3=r3/2 =k using ratios Hence r1=6k, r2=3k r3=2k Hence using the property of solution of trianle the required triangle is equilateral. Please feel free to ask … 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. bitch 3.0 testo
