What is the most difficult part of teaching geometry? Proofs! We all know how much children can struggle with even the most basic proofs. This cheat sheet was designed to help students work through geometric proofs with a little bit of scaffolding. We encourage our students to use it until they are more comfortable with the language we expect in proofs.
This is also an excellent resource for teachers teaching geometry for the first time.
The following givens are addressed:
Parallel lines (leading to Alternate Interior Angles)
Parallel lines (leading to Alternate Exterior Angles)
Parallel lines (leading to Corresponding Angles)
