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.
