Geometry: Parallel Lines, Transversals, and Special Angle Pairs

It has taken me about three years to grasp the point of this unit. The angle relationships are later used in Unit 6 Quadrilaterals and Unit 7 Properties of Two Dimensional Figures.

I have noticed in the past that students sometimes struggle with all the numbers assigned to the angles. A fellow teacher at a math and science symposium shared this star-dot labeling she has used in the past. She said that this is to be used once an exploratory is complete where a student builds an understanding of congruent and supplementary angles. This allows the students to quickly relate two symbols with location instead of dealing with the numbers.

Geometry: Angle Relationships

Pg 15. Angle Addition Postulate

The bottom half is a manipulative used to physically demonstrate the Angle Addition Postulate. The yellow rectangle was glued down 'like a pocket' for angles 1 and 2.

I use the layered flip book quite a bit.
