Exploring the Pythagorean Theorem

In this video, Mr. Jay provides a visual representation of the Pythagorean theorem using a right triangle with side lengths of 4, 3, and 5 feet. He explains how to identify the triangle's sides as a, b, and c, and demonstrates the theorem by squaring these sides to form squares. The video shows that the sum of the areas of the squares on the two shorter sides equals the area of the square on the hypotenuse. Mr. Jay verifies the equation a² + b² = c² with these values, confirming the theorem's validity for all right triangles.

What equation is used in the Pythagorean theorem?

• a^3 + b^3 = c^3

• 2a + 2b = c

• a^2 - b^2 = c^2

• a^2 + b^2 = c^2

What does the hypotenuse represent in a right triangle?

• The longest side

• The shortest side

• Both A and C

• The side opposite the right angle

How do the areas of the squares on the legs compare to the area of the square on the hypotenuse?

• They are more

• They are equal

• They are less

• They add up to the area of the square on the hypotenuse
