The video tutorial explains how to calculate the area and perimeter of triangles. It covers the formula for area as 1/2 base times height and discusses the use of the Pythagorean theorem to find the perimeter of right triangles. The tutorial also addresses how to handle cases where the height is not directly given, such as in oblique triangles, and emphasizes the importance of correctly identifying base and height by rotating the triangle if necessary.
