PRODUCT DESCRIPTION

With over a hundred different theorems, postulates, and definitions in geometry, it can be overwhelming to know where to start. I decided to create Geometry Proof Attack Sheets that can help a student hone in on which of all those theorems, postulates, and definitions are needed to complete a proof. Students will need to do four basic things to attack proofs:

1. Think
2. Plan
3. Do!
4. Check

Using these steps, I outlined some questions that students can ponder on as they attack a proof. Refer to the Think, Plan, Do, Check sheets to see the leading questions. You'll find a blank one as well to have students fill in with their own words as you teach them how to think through a proof. I also included a poster to display to remind your students of the above steps.

Each page has a shape or figure that is typically used in geometry proofs. The pages do not include a specific proof, but general theorems, postulates, and definitions that are helpful when solving a proof for that particular shape. I am going to repeat myself: Not all possible definitions, theorems, and postulates are written on each attack sheet. I chose to list the most commonly used ones for each shape or figure.

Attack Sheets Included:

Lines & Angles
Triangles
Parallelogram
Square/Rhombus
Rectangle
Kite
Trapezoid
Circles

These attack sheets were made to help guide thinking, not replace it. Solving proofs takes practice! I hope these sheets will help your students like they have helped mine!
