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: c² = a² + b².

How do you find the length of the hypotenuse in a right triangle?

Back

To find the length of the hypotenuse in a right triangle, use the Pythagorean Theorem: c = √(a² + b²), where c is the hypotenuse and a and b are the lengths of the other two sides.

What is the relationship between the sides of a right triangle?

Back

In a right triangle, the lengths of the sides must satisfy the Pythagorean Theorem. If a, b, and c are the lengths of the sides, then a² + b² = c², where c is the hypotenuse.

How can you determine if a set of numbers can represent the sides of a right triangle?

Back

To determine if a set of numbers can represent the sides of a right triangle, check if the largest number squared is equal to the sum of the squares of the other two numbers. This follows the Pythagorean Theorem.

If a triangle has sides of lengths 5, 12, and 13, is it a right triangle?

Back

Yes, it is a right triangle because 5² + 12² = 25 + 144 = 169, which equals 13².
