What is the relationship between the sides of a right triangle and the Converse of the Pythagorean Theorem?

Back

The Converse states that if the square of the longest side equals the sum of the squares of the other two sides, the triangle is a right triangle.

What is the result of checking the sides 18, 73, and 75 for being a Pythagorean Triple?

Back

No, because 18^2 + 73^2 = 324 + 5329 = 5653, which does not equal 75^2 (5625).
