What is an equilateral triangle

The video tutorial explains how to classify triangles based on their sides. It begins with a general introduction to triangle classification and then focuses on equilateral triangles, which have three equal sides. The tutorial describes how to identify equilateral triangles using tick marks to denote equal sides and emphasizes the concept of equal angularity in relation to equilateral triangles.
