The video tutorial introduces Pythagorean triples, which are sets of whole numbers that satisfy the Pythagorean theorem. It explains the basic concept using the 3-4-5 triangle and explores how multiples of these triples can be used to solve right triangles quickly. The tutorial covers common triples like 5-12-13 and 7-24-25, as well as less common ones such as 9-40-41. It also touches on very uncommon triples, emphasizing that memorizing the most common ones is sufficient for most problems.

What is the Pythagorean theorem used for in a right triangle?

• To calculate the area of the triangle

• To measure the angles of the triangle

• To determine the type of triangle

• To find the length of one side when the other two sides are known
