Question
What will be inradius of a right angle triangle whose base is 3 cm & height is 4 cm ?
By pythogorus theorem, Hypotenuse 2 = Base 2 +Height 2 = 32 + 42 = 9 + 16 = 25, So Hypotenuse = 5; Now inradius of a right angle triangle = (Base + Height - Hypotenuse)/2 = (3 + 4 - 5)/2 = 2/2 = 1 cmMore Geometry Questions
