Why are we taught the Pythagorean Theorem?

The Pythagorean Theorem is an important mathematical concept that is taught in schools because it provides a way to calculate the length of the sides of a right triangle. It is a fundamental tool for solving many problems in geometry, trigonometry, and algebra. Knowing the Pythagorean Theorem can help students understand the relationships between the sides of a triangle and the angles of a triangle. It can also be used to calculate the area of a triangle and the volume of a pyramid.
