*This is the 4th unit in my Geometry curriculum. It may be beneficial for students to complete Units 1-3 before starting this course.*
Now that you have learned how to create segment proofs, you can now work with angles and angle proofs. You should feel comfortable with all types of basic proofs by the end of this unit. Like in Unit 3, memorization of all of these angle Properties, Postulates, Theorems, and Definitions is necessary.
This Unit will discuss how to identify and name angles, and how to find angle measures. It will incorporate the use of variables into the examples. After completing this unit, you should feel confident to approach any angle problem.
The lessons in this unit cover: Introduction to Angles, Finding Angle Measure, Angle Vocabulary, Algebra and Angles, and Angle Properties and Proofs.
