Classifying Triangles Based on Sides' Length

The video tutorial explains how to classify triangles based on their angles and side lengths. Triangles can be categorized into right, obtuse, and acute based on angles, and into equilateral, isosceles, and scalene based on side lengths. Equilateral triangles have all sides and angles equal, isosceles triangles have two equal sides and angles, and scalene triangles have no equal sides or angles. The tutorial also discusses combining these classifications, such as right isosceles triangles.
