Classifying and Identifying Triangles by Angles and Side Lengths

The video tutorial explains how to classify triangles based on their angles and side lengths. It covers three types of triangles by angles: acute-angled, obtuse-angled, and right-angled. It also discusses three special types of triangles by side lengths: equilateral, isosceles, and scalene. Each type's properties, such as angle measures, side lengths, and symmetry, are detailed. The importance of recognizing these properties for calculating missing angles is emphasized.
