Find the volume of a triangular prism and cube
: In this tutorial we'll practice finding solid geometry volume. Keep paper and pencil nearby in case you want to remember the formulas.
Practice with area, volume, and surface area
Complementary and supplementary angles
: Let's add some tools to our geometry tool belt. Here's a thorough explanation of complementary and supplementary angles, as well as definitions of adjacent and straight angles.

Complementary and supplementary practice
Introduction to vertical angles
: By using our knowledge of supplementary, adjacent, and vertical angles, we can solve problems involving the intersection of two lines. Including this one!
Find measure of vertical angles
: Given two intersecting lines and the measure of vertical angles, watch as we solve to find the measure of the remaining angles.
Solving for unknown angles practice
Construct a triangle with constraints
: Here's a challenge: in this problem we are given constraints and asked to construct a triangle. It can be done! You'll learn about degenerate triangles, too.

Volume: measuring as area times length
: Sometimes, we can't just count the number of cubes to find the volume because there are too many. In those situations, you need another way of measuring volume. This video gives you the solution.
Volume: how measure it
: Volume is a measurement in the 3rd dimension. This means that it not only has width and height, but it has depth as well. Let's watch this video in which we get a great explanation of how we measure volume.
