Question
What will be inradius of a right angle triangle whose base is 20 cm & height is 21 cm ?
By pythogorus theorem, Hypotenuse 2 = Base 2 +Height 2 = 202 + 212 = 400 + 441 = 841, So Hypotenuse = 29; Now inradius of a right angle triangle = (Base + Height - Hypotenuse)/2 = (20 + 21 - 29)/2 = 12/2 = 6 cmMore Geometry Questions
