How to label triangles depending on the length of their sides

The video tutorial discusses the classification of triangles based on the equality of their sides. It introduces three types of triangles: equilateral, where all sides are equal; isosceles, where two sides are equal; and scalene, where no sides are equal. The teacher explains how to identify these triangles using tick marks to denote equal sides and concludes with a review, preparing students for a test on the material.
