In this video, Mr. Jay explains how to use the Pythagorean theorem to find the length of a missing leg in a right triangle. He provides two examples, demonstrating the step-by-step process of solving for the missing side using the formula a² + b² = c². The video concludes with a summary of the method and its application.

What is the formula for the Pythagorean Theorem?

• a^2 - b^2 = c^2

• a^2 + b^2 = 2c

• 2a + 2b = c^2

• a^2 + b^2 = c^2
