Introduction

To build a house, one must start with a blueprint. A blueprint is a drawing with a vision of what the actual house will be.

Geometry is the branch of mathematics that deals with the properties, measurement, and relationships of

  • lines,
  • angles,
  • points,
  • surfaces, and
  • solids.

So what’s the point? Why do we study geometry? As you envision what Geometry is about, look around you and think of a geometry term you feel you understand.

Lesson Objectives

Following successful completion of this lesson, students will be able to...

  • Identify and name points, lines, segments, rays, and planes
  • Identify and name terms based on the undefined terms in geometry
  • Identify parallel, perpendicular, and skew lines

Essential Questions

  • How do properties of lines and angles relate to basic shapes?
  • How can you find the lengths and midpoints of segments?
  • How can you measure of angles?
  • How can lines and angles be classified?

Enduring Understandings

  • Everything is built from points, lines, and planes and follows very strict and organized rules.

The above objectives correspond with the Alabama Course of Study: Geometry standard: 30.
