The Pythagorean Theorem and the Coordinate Plane

The video tutorial explains how to use the Pythagorean theorem to find the length of a diagonal segment in a coordinate plane. It begins with a problem involving triangle PTU and segment TU. The instructor demonstrates forming a right triangle and applying the Pythagorean theorem to calculate the hypotenuse. The process involves counting the lengths of the triangle's legs, calculating the hypotenuse, and rounding the result to the nearest unit.
