Standards Addressed: MGSE.9-12.G.CO.9 Prove theorems about lines and angles. Theorems include vertical angles are congruent, when a transversal crosses parallel lines, alternate exterior angles are congruent and corresponding angles are congruent.; points on a perpendicular bisector of a line segment are exactly those equidistance from the segment’s endpoints.

Learning Targets /Success Criteria I can solve problems involving parallel lines cut by a transversal.
• I can recognize and apply properties of the alternate interior angle theorem.
• I can recognize and apply properties of the alternate exterior angle theorem.
• I can recognize and apply properties of the same side interior angle theorem.
• I can recognize and apply properties of corresponding angles postulate.

Introduction/Connection (Bellringer): students will complete Similarity & Geometric Relationships (attached below)

Direct Instruction/Guided Practice
--Review bellringer
--Guided practice using Parallel lines with Transversal w/s (attached below). Students will finish in collaborative pairs.


Independent Practice/Collaboration/Differentiation
--Differentiation: foldable, color code congruent angles, provide one-on-one assistance for struggling students, provide material for accelerated learners, student-led review/teaching.
--Students will complete Similarity and Geometric Relationships (Lesson 1-3 w/s)
--Students will complete selected problems on Parallel Lines w/ a Transversal practice w/s.

Summarizer/CFU: Naming angle pairs: identify a pair of corresponding angles, etc.

Assignment:
1) selected problems on Parallel Lines w/ Transversal w/s (attached below)
2) "Pop" quiz on parallel lines/transversal
