Exploring the Pythagorean Theorem: Finding a Leg

The video tutorial reviews the Pythagorean theorem, focusing on finding the hypotenuse and missing legs in right triangles. It also covers using the theorem for diagonals in rectangles. The instructor provides step-by-step examples and concludes with assignment instructions.

What is the formula for the Pythagorean theorem?

• a^2 / b^2 = c^2

• a^2 + b^2 = c^2

• a^2 - b^2 = c^2

• a^2 * b^2 = c^2

How do you find a missing leg if you know the hypotenuse and the other leg?

• Multiply the squares of the hypotenuse and the known leg and take the square root

• Divide the square of the hypotenuse by the square of the known leg and take the square root

• Add the squares of the hypotenuse and the known leg and take the square root

• Subtract the square of the known leg from the square of the hypotenuse and take the square root
