Types of Triangles and Their Properties

The video tutorial reviews three types of triangles: equilateral, isosceles, and scalene. An equilateral triangle has all sides equal, an isosceles triangle has two equal sides, and a scalene triangle has no equal sides. The tutorial includes an exercise to identify triangle types based on their properties.
