# Ch 11: High School Geometry: Geometric Solids

Use video lessons with quizzes to learn about the various aspects of geometric solids. These easy-to-follow lessons are just a portion of our online study guide and video collection.

## High School Geometry: Geometric Solids - Chapter Summary and Learning Objectives

Geometry is used in various professions, like drafting, architecture, astronomy, medical imaging or graphic design. This chapter explores how planes and lines behave in space. You can learn to define and illustrate many platonic solids, including tetrahedron, hexahedron, octahedron, dodecahedron and icosahedron. You can also meet many other geometric solids, learning to not only define and illustrate them, but also investigating the formulas for their surface areas, volumes or lateral areas. At the end of this chapter, you should be able to:

• Define a polyhedron and give examples
• Define and illustrate five types of platonic solids
• Define and illustrate a prism, pyramid, right circular cylinder, right circular cone and a sphere; explain how to calculate the surface area and volume of each, giving examples
• Discuss the formulas for lateral area of a pyramid, cylinder and cone
