Solving Pythagorean Theorem Word Problems

The video tutorial focuses on the Pythagorean theorem, explaining its formula and application in solving word problems. It begins with a basic problem involving a right triangle, followed by three practical examples: calculating the length of a ladder leaning against a wall, determining the width of a TV screen, and finding the length of a zipline. Each example demonstrates how to apply the theorem to real-world scenarios, reinforcing the concept of using a squared plus b squared equals c squared to find unknown side lengths in right triangles.

What is the formula of the Pythagorean theorem?

• 2a + 2b = c^2

• a^2 - b^2 = c^2

• a^2 + b^2 = 2c

• a^2 + b^2 = c^2
