Exploring the Pythagorean Theorem

This video tutorial covers the Pythagorean Theorem, explaining its formula and application in right-angled triangles. It includes examples of finding the hypotenuse and a leg of a triangle, as well as applying the theorem to 3D shapes like pyramids. The video emphasizes the importance of identifying the hypotenuse and provides practice problems for viewers.

Why must the hypotenuse always be the longest side in a right-angled triangle?

• It is the shortest side

• It is opposite the right angle

• It is the base of the triangle

• It is always a perfect square

In the context of a square pyramid, what does the slant height represent?

• The length of the base's diagonal

• The height of the pyramid

• The height from the base to the apex

• The length from the base's center to a vertex along the surface
