Reflection: Intervention and Extension Parallel Lines Intersected by a Transversal - Section 4: Summary


This was a very difficult concept for my students and at first they were hesitant to try to make sense of the statement. We worked together to deconstruct the statement and break it down into smaller, more manageable parts. The students discussed the statement together and wrote an explanation. They then shared out their explanations with the class and we developed a full explanation together. I was very impressed with my students ability to persevere and try to make sense of a difficult concept.

Parallel Lines Intersected by a Transversal

Unit 6: Introduction to Geometric Proofs
Lesson 8 of 10

Objective: SWBAT write simple formal proofs about angles formed by two parallel lines intersected by a transversal.

Big Idea: Students will build on prior knowledge about the relationships between angles and parallel lines to write formal proofs.
