30 question thorough worksheet assessing whether students know the postulates and theorems surrounding proving lines parallel using angles formed by transversal. Lots of algebraic problems as well.
This product does not have 2-column proofs. If you are looking for those, please check out my Proofs Packet #2 - https://www.teacherspayteachers.com/Product/Geometry-Proofs-Packet-2-Proving-Lines-Parallel-3417638
2 versions with one page of extra proofs that can be attached to either version.
Parallel lines and angles formed by transversal
This was created with Pearson TestGen software using my own personal testbank
This covers common theorems, postulates, and definitions pertaining to perpendicular lines. The last two pages have proofs that include complementary angle theorem and can be removed easily if students have not yet learned the material.
There are many proofs at the end. Key included.
3 different versions of a worksheet on: complementary angles, supplementary angles, vertical angles, and linear pairs
1 extra version that is all proofs - none are repeats from previous worksheets
12 unique proofs
Conditional statements, converses, biconditionals, and counterexamples
3 versions - created with Pearson TestGen software using my own personal testbank
Basic Angle Addition Postulate and notation/parts of angles.
3 versions with keys - this was created with Pearson TestGen software using my own personal testbank
3 versions with keys - Versions A+B are similar and easy. Version C is challenging. All worksheets were created with Pearson TestGen software using my own personal testbank
8 pages (with corresponding answer keys) of in-depth partially completed proofs containing properties of algebra, postulates, theorems, and definitions from segments and angles to perpendicular lines (not parallel). Perfect for testing if students are getting the hang of proofs. Works well as a group activity.
A short pre-proof activity that uses algebra to begin the concept of proving using statements and reasons. This was made in Microsoft 2013 and converted to PDF. Key included
This activity practices finding equations of lines using point-slope or slope-intercept. Includes an answer bank with all potential answers plus a few extra. Includes a key with all potential answers.
This is a great differentiated activity to sum up equations of lines while allowing flexibility for students to pick the method (point-slope or slope-intercept) with which they are most comfortable!
