Question

A triangle has sides with lengths of 7 meters, 24 meters, and 25 meters. Is it a right triangle?

Answer 1

As `25^2=7^2+24^2` it is a square triangle.

Explanation:

if it were a right triangle, then the theorem of Pytagoras would apply and then:

`7^2+24^2` would be equal to `25^2`

In fact:

`7^2+24^2 = 625`
`25^2=625`

and so the triangle is a right triangle.
