How A Triangle With Sides 7 cm, 24 cm, and 25 cm Works With the Pythagorean Theorem

At the heart of geometry lies a simple but profound truth: in a right triangle, the square of the longest side (the hypotenuse) equals the sum of the squares of the other two sides. For a triangle with sides 7 cm, 24 cm, and 25 cm, testing this Mantra reveals its nature.

7 squared is 49.
24 squared is 576.
25 squared is 625.

Key Insights

Adding 49 and 576 gives 625—exactly equal to 25 squared. This mathematical balance confirms the triangle follows the Pythagorean theorem, confirming it is, indeed, a right triangle.

This strong indication invites exploration beyond the formula. The 7-24-25 measurement forms a well-known Pythagorean triple, a validated set where all sides fit the geometric and algebraic rules consistently. It’s a reliable example used in classrooms and tutorials to demonstrate hypothesis testing in geometry.
