Question

A triangle has sides with lengths of 12 yards, 16 yards, and 20 yards. Is

Answer 1

Yes, it is right angle triangle.
We can know by using pythagoras theorem
So let’s see
Let the highest length be hypotenuse, and 12 yards be base now,

h^2 = p^2 + b^2
20^2 = 16^2 + 12^2
400 = 256 + 144
400 = 400
Hence
It is a right triangle.
