Instructional Ideas
- Create collaborative groups to complete the set of six proofs, with one proof for each group to put on the board for analysis
Classroom Considerations
- Provide guidance through the completion of the proofs to improve confidence
- Create fill-in-the blank proofs or envelop proofs to build confidence before attempting the proofs individually
- Previous experience with basic triangle congruence proofs is required
Pros
- The proofs provided have a progressive level of difficulty
Cons
- Guidance for instruction is not provided; the content of the lesson is six proofs to be completed individually
