He discovered the Pythagorean Theorem.

It is the longest side of a right triangle.

Which of the following is the formula of Pythagorean Theorem?

• c² = a² + b²

• c² = a² - b²

• c² = b² - a²

• c² = a²/b²

What is the formula if a is missing?

• a = √b² - c²

• a = √c² - a²

• a = √c² - b²

• a = √c² + b²

Find the formula of c is missing.

• c = √b² - a²

• c = √a² - b²

• c = √a² + b²

• c = √c² + a²

Determine the formula if b is lacking.

• b = √c² + a²

• b = √a² - c²

• b = √c² + b²

• b = √c² - a²
