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 is expressed as a² + b² = c².

If a right triangle has legs of length 3 and 4, what is the length of the hypotenuse?

Back

Using the Pythagorean Theorem: c² = 3² + 4²; c² = 9 + 16; c² = 25; c = 5.

What are Pythagorean Triples?

Back

Pythagorean Triples are sets of three positive integers (a, b, c) that satisfy the Pythagorean Theorem, meaning a² + b² = c².

Are the numbers 8, 15, and 17 a Pythagorean Triple?

Back

Yes, because 8² + 15² = 64 + 225 = 289 = 17².

What is the length of the missing side if one leg is 6 and the hypotenuse is 10?

Back

Using the Pythagorean Theorem: c² = a² + b²; 10² = 6² + b²; 100 = 36 + b²; b² = 64; b = 8.

If a = 5 and b = 12, what is c?

Back

Using the Pythagorean Theorem: c² = 5² + 12²; c² = 25 + 144; c² = 169; c = 13.

What is the formula to find the length of one leg of a right triangle if the other leg and the hypotenuse are known?

Back

The formula is a² = c² - b², where c is the hypotenuse and b is the known leg.
