Triangle Types and Distance Calculations

This tutorial video explains how to use the distance formula to classify triangles. It begins with an introduction to the distance formula and its application in determining triangle types. The video then demonstrates graphing a triangle using given points and calculating the distances between its vertices. The Pythagorean theorem is applied to verify the triangle's type, and the video concludes with classifying the triangle as scalene, isosceles, or equilateral based on the calculated side lengths.
