Question
What will be inradius of a right angle triangle whose
base is 15cm & height is 8cm ?Solution
By pythogorus theorem, Hypotenuse 2 = Base 2 +Height 2 = 15 2 +8 2 = 225 + 64 = 289, So Hypotenuse = 17; Now inradius of a right angle triangle = (Base + Height - Hypotenuse)/2 = (8 + 15 - 17)/2 = 6/2 = 3cm
