This video tutorial covers the main types of triangles: equilateral, isosceles, scalene, and right-angled. It explains the characteristics of each type, such as the number of equal sides and angles. The video also discusses how triangles can appear in different orientations and how to identify right-angled triangles. The tutorial concludes with a question about the possibility of a triangle having two right angles.
