# Pythagorean Theorem: Concept and Uses

TOPICS: Pythagorean Theorem Concepts     Uses of the Pythagorean Theorem

To really understand the Pythagorean Theorem we have to be clear on some concepts. For example, it only applies to right triangles; in other words, triangles that have a right angle. We also have to know what the names given to the sides of a right triangle are: the sides that form the right angle are called legs, while the side opposite the right angle is called the hypotenuse.

Another important aspect of the Pythagorean Theorem has to do with its uses. This theorem is used for a large number of situations to find unknown measurements which otherwise couldn’t be calculated exactly or which would take a long time to measure.

In the video included below, the Pythagorean Theorem is explained in great detail and in a very simple way, as well as all concepts related to this theorem that you have to know in order to understand it well. It also shows many uses and applications for the theorem and how it turns out to be very useful to solve a large number of problems. Now, on with the video!
