Pythagorean Theorem

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 a missing leg in a right triangle?

Back

To find a missing leg (a or b), rearrange the Pythagorean Theorem: a = √(c² - b²) or b = √(c² - a²).

If one leg of a right triangle is 3 cm and the other leg is 4 cm, what is the length of the hypotenuse?

Back

5 cm (using the Pythagorean Theorem: c = √(3² + 4²) = √(9 + 16) = √25 = 5).

If the hypotenuse of a right triangle is 10 cm and one leg is 6 cm, what is the length of the other leg?

Back

8 cm (using the Pythagorean Theorem: b = √(10² - 6²) = √(100 - 36) = √64 = 8).
