Requirements
  • Students should have taken Units 1 and 2 before starting this unit
  • This is a continuation of my Geometry curriculum
Description

*Please note, this is a continuation of my first two curriculum units in Geometry. To be successful, it may be necessary to work through the first two units.*

Now that you know the basics, we can begin working through segment proofs. Memorizing the properties, postulates, and theorems is necessary for success in Geometry. I have attached a handout to assist you throughout the lessons, but memorization of these Postulates, Properties, Theorems, and Definitions is necessary.

After competing this Unit, you will be able to use postulates to prove that geometric statements are always, sometimes, or never true. You will also be able to use properties of segments to prove segment relationships in a formal, two-column proof.

In this Unit, there are three lessons. These lessons cover: Postulates, Properties and Proofs, and Segment Proofs.

Who is the target audience?
  • Geometry students
  • Geometry teachers
  • Adult Education (GED/HSE) learners

Math Teacher

I am a High School Math and High School Equivalency teacher in Las Vegas, Nevada. I just finished my 4th year of teaching. My background is in math and science (B.S. in Science and Math Education, M.Ed. in Agriculture Education from North Carolina State University). I recently started a Ph.D. program at the University of Nevada, Las Vegas in Curriculum and Instruction with an emphasis in Math Education.
