Classifying Different Types of Triangles

The video tutorial teaches students how to classify triangles based on their sides and angles. It covers equilateral, isosceles, and scalene triangles for side classification, and acute, obtuse, and right triangles for angle classification. The tutorial includes practice problems to reinforce learning.

• One side longer than the other two

• Three sides of the same length

• Two sides of the same length

• Three sides of different lengths
