How do you determine from points what type of triangle you have

The video tutorial explains how to determine the type of a triangle formed by three points using the distance formula. It begins with an introduction to different triangle types: equilateral, isosceles, and scalene. The instructor plots points on a graph and discusses initial observations. Since the points do not align horizontally or vertically, the distance formula is applied to calculate the distances between each pair of points. The instructor performs calculations to confirm that the triangle is scalene, as all sides have different lengths.
