take all the sides in the ratio- 3x,4x,5x
it follows that (5x)^2 = (4x)^2 + (3x)^2
so it follows the pythagoras theorem so largest angle is 90

according to pythagoraus theorem
(AC)2 = (AB)2 + (BC)2
(5x)2 = (3x)2 + (4x)2
25x2 = 9x2 + 16x2
25x2 = 25x2
so it follows pythagoraus theorem
so it must be a right angle and the largest angle of the triangle is 900
