Use the pythagorean theorem to determine the if a triangle with side lengths 4ft., 10 ft., and 12ft. is a right triangle?

We can use Pythagoras Theorem to prove that a triangle is a right-angle triangle if the square of the two shorter legs add up to be the square of the longest leg.

In this case, we need to prove that 4² + 10² = 12²

Pythagoras Theorem:









Therefore a triangle with side lengths 4 ft, 10ft and 12 ft is not a right angle triangle.

It says in the questions that it is 6.5?

Ithink it is15not sure tho
