Distance and Properties of Triangles

The video tutorial explains how to prove a triangle is a right angle triangle using the distance formula. It begins with an introduction to the concept, followed by a detailed explanation of the distance formula. The instructor then calculates the distances of the triangle's sides and applies the Pythagorean theorem to verify the right angle. The tutorial concludes with a discussion on alternative methods for proving geometric properties.
