Q. 3

# Write whether Tru

We have

This is a right circular cone, with

Height = h

And slant height = l

We know, AOB = 90°

So by using Pythagoras theorem in ∆AOB, we can write

AB2 = AO2 + OB2

l2 = h2 + r2

This justifies that height, radius and slant height of cone can always be the sides of a right triangle.

Hence, it is true.
