What will be inradius of a right angle triangle whose base is 13 cm & height is 84 cm ?
By pythogorus theorem, Hypotenuse 2 = Base 2 +Height 2 = 132 + 842 = 169 + 7056 = 7225, So Hypotenuse = 53; Now inradius of a right angle triangle = (Base + Height - Hypotenuse)/2 = (13 + 84 - 85)/2 = 12/2 = 6 cm
