The main focus is on recognizing the mathematical relationship between the sides of a right triangle.

Key Concept Explanation:
The Pythagorean Theorem states that in a right triangle, the square of the hypotenuse equals the sum of the squares of the two legs: where a and b are the legs, and c is the hypotenuse.

Step-by-Step Solution:
