Supplementary and vertical angles explained. We look at a variety of "angle puzzles", or problems with an unknown angle, and solve those using these basic principles. I also write an equation for each problem, to help students learn to both write and solve equations, since this lesson belongs to my pre-algebra course. (See )

The first problem involves finding the volume of a house. We do that in two parts: the bottom part is a rectangular prism, and the top part is a triangular prism. The second problem has to do with finding the volume of water in a pool. Find more 7th grade math videos at Math Mammoth Grade 7 curriculum:

The volume of both prisms and cylinders is calculated with the same formula: The volume is the area of the base times its height. In this video, we calculate first the volume of a right triangular prism, and then the volume of a cylinder. Find more 7th grade math videos at Math Mammoth Grade 7 curriculum:
