please help me with this math thing

Proving the converse of the Pythagorean Theorem means proving that if the sum of the squares of the lengths of the shorter sides of a triangle equals the square of the length of the longest side, then the triangle is a right angle triangle.
Here's the equation:
(short side)² + (short side)² = (long side)²
Answer:
Sum, Shorter, and Longest.
Step-by-step explanation:
A Pythagorean triple [tex](a,b,c)[/tex] is a set of three positive whole numbers which satisfy the equation
[tex]a^2 + b^2 = c^2.[/tex]
Many ancient societies employed Pythagorean triples like (5,6,7) to precisely create right angles: if a triangle has sides of lengths 5, 6, and 7 units, respectively, the angle opposite the side of length 5 units is therefore a right angle.
