What is the Pythagorean Theorem?

Back

The Pythagorean Theorem states that in a right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides (a and b). It can be expressed as: a² + b² = c².

How do you classify a triangle with side lengths 5, 12, and 13?

Back

This triangle is a right triangle because it satisfies the Pythagorean Theorem: 5² + 12² = 13² (25 + 144 = 169).

What is the converse of the Pythagorean Theorem?

Back

The converse of the Pythagorean Theorem states that if a triangle has side lengths a, b, and c, and a² + b² = c², then the triangle is a right triangle.

What is the length of the hypotenuse in a right triangle with legs of lengths 6 and 8?

Back

The length of the hypotenuse is 10, calculated using the Pythagorean Theorem: 6² + 8² = c² (36 + 64 = 100, so c = 10).
