Geometric shapes are all around us. The world is built with them. In this series of tutorials and exercises you'll become familiar with Euclidean geometry and terms like segments, scale drawings, parts of a circle, area, volume, angles, and geometric figures.
Try some practice problems
Learn by doing or check your understanding

Learn to find volume of rings, triangular prisms, and rectangular prisms inside of other rectangular prisms.

Practice finding missing angles in figures using your knowledge of vertical, supplementary, and complementary angles.

When we slice (cut through) a 3D shape, we make a 2D shape called a cross section. In this tutorial, we think about the different cross sections we can make by slicing 3D shapes.

A map depicts objects much smaller than they are in real life. A map is a great example of a scale drawing. In this tutorial, we'll take a mathematical look at the nature of scale drawings.
