Triangles

This math video provides an introduction into triangles. It explains the classification of triangles based on their angle measure and the number of congruent sides. Examples include equilateral triangles, scalene triangles, isosceles, right, acute, and obtuse triangles. This video also contains practice problems on solving the angle measure of triangles.
