Types and Properties of Triangles

The video tutorial introduces the classification of triangles based on their side lengths. It explains scalene triangles, which have all sides of different lengths, isosceles triangles with two equal sides, and equilateral triangles where all sides are equal. The tutorial also provides the etymology of these terms and encourages creative exploration of triangle types using a box of sticks.
