Pythagorean Theorem

Front

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.

What is the formula to find the hypotenuse of a right triangle?

Back

The formula to find the hypotenuse (c) of a right triangle is c = √(a² + b²), where a and b are the lengths of the other two sides.
