### PRODUCT DESCRIPTION

Are you introducing proofs for the first time? Are your students struggling with the concept of a proof? I have found that there are very few remediation worksheets on proofs and sometimes it is necessary to go slow until all students get the hang of proofs. It can be frustrating when the textbooks only include one or two examples.

I created this very straightforward study guide for beginner proofs on the the common angles formed by 2 parallel lines cut by a transversal line. This particular study guide contains 12 proofs.
The first few are quite simple and only contain 2 givens and one additional statement. The second half is slightly harder and requires the students to use the Linear Pair Theorem to ultimately set up an equation about supplementary angles in order to prove facts about the angles in question.

**There are several ways to complete the last 5 or 6 proofs. I have included one option but your students may come up with something slightly different using a different set of angle pairs.

The proofs are easy and repetitive but some contain 9 steps each. I have used this in my own classroom and it is a good way for the kid that proofs themselves can be repetitive once you get the "hang of it."
Please check out my other proof packets that I have posted and stay tuned for a lot more coming soon! If you are happy with your download I would appreciate any positive feedback you would be willing to leave. Thanks and happy teaching!
