Understanding the Pythagorean Theorem

The video tutorial explains the Pythagorean theorem, detailing how to calculate the missing side of a right triangle using the formula a² + b² = c². It covers finding the hypotenuse and a missing leg, emphasizing the importance of logical checks and using square roots to solve for unknowns.

What is the formula for the Pythagorean Theorem?

• a^2 + b^2 = c

• a + b = c^2

• a^2 + b^2 = c^2

• a^2 + b = c^2
