## Introduction

In this chapter, students will learn about the building blocks of geometry. We will start with what the basic terms: point, line and plane. From here, students will learn about segments, midpoints, angles, bisectors, angle relationships, and how to classify polygons.

## Chapter Outline

- 1.1. Basic Geometric Definitions
- 1.2. Distance Between Two Points
- 1.3. Congruent Angles and Angle Bisectors
- 1.4. Midpoints and Segment Bisectors
- 1.5. Angle Measurement
- 1.6. Angle Classification
- 1.7. Complementary Angles
- 1.8. Supplementary Angles
- 1.9. Linear Pairs
- 1.10. Vertical Angles
- 1.11. Triangle Classification
- 1.12. Polygon Classification

### Chapter Summary

## Summary

This chapter begins with the basic components of Euclidean Geometry. From the introductory definition of points, lines, and planes it builds to a discussion of classifying figures such as angles, triangles, and polygons. Measurement of distances and angles are also covered. Different types of angle relationships are compared and explored, such as complementary angles, supplementary angles and linear pairs.
