Learning to classify a triangle given three points

The video tutorial covers the classification of triangles based on their sides: equilateral, isosceles, and scalene. It explains how to plot points on a graph to determine the type of triangle formed. The tutorial emphasizes the importance of using the distance formula to calculate the exact lengths of triangle sides, rather than estimating. The process of calculating distances between points is demonstrated, highlighting the use of the distance formula in geometry.
