Triangle Classification and Types

This video tutorial continues with the CUDA software worksheet on classifying triangles. It covers how to classify triangles by their angles (acute, obtuse, right) and sides (scalene, isosceles, equilateral). The video provides detailed explanations and examples for each type, followed by practice problems to reinforce learning. The tutorial also offers tips for identifying angles using everyday objects.
