Question
What will be inradius of a right angle triangle whose
base is 12 cm & height is 35 cm ?Solution
By pythogorus theorem, Hypotenuse 2 = Base 2 +Height 2 = 122 + 352 = 144 + 1225 = 1369, So Hypotenuse = 37; Now inradius of a right angle triangle = (Base + Height - Hypotenuse)/2 = (12 + 35 - 37)/2 = 10/2 = 5 cm
