Identifying and Classifying Triangles

This video tutorial teaches how to classify triangles based on their sides and angles. It covers three types of triangles by sides: scalene, isosceles, and equilateral, and three types by angles: acute, right, and obtuse. The video explains how to identify these triangles using visual markers and measurements. It concludes with a call to action for viewers to engage with the content by leaving feedback or asking questions.
