Teacher letter citing standard 8.G.A.5 and listing 24 scavenger hunt cards, a student answer sheet and an answer key
Read first: standard alignment and list of included parts
Cover: Angle Relationships in Similar Triangles, Exterior Angles, and Parallel Lines & Transversals Scavenger Hunt
Title page for the walk-around review activity
Scavenger hunt setup steps: print and post cards, number students 1-24, let them follow the hunt, then show answer order
Teacher prep and room setup before the hunt
Cards 1-2: pick the corresponding angle pair where transversal t cuts parallel lines, then find exterior angle CAD
Opening cards: each answer choice sends students to the next card
Cards 3-4: use Angle-Angle to choose which two of triangles A-D are similar, then find angle X and justify it
Post around the room; students justify angle answers
Cards 5-6: with BD parallel to AE, find angle BCD by the exterior angle theorem and classify triangles ACE and BCD
Mid-hunt cards pairing exterior angles with similarity
Cards 7-8: find angle AED in a triangle cut by parallel segment BD, then find angle M from a 140° exterior angle
Hunt stops on computing missing angle measures
Cards 9-10: decide if triangles EFG and IHG are similar or congruent, then name the shaded angle pair
Cards mixing triangle similarity and transversal angle pairs
Cards 11-12: pick the false statement about a triangle's exterior angles, then compare right triangles ABC and SRQ
Later hunt cards on angle sums and right-triangle similarity
Student answer sheet: 12 spaces where students write each card number and answer in the order they follow the hunt
Hand one to each student to track their path

About This Product

This resource was developed to meet the requirements of the 8th Grade Geometry Standard below:

CCSS.MATH.CONTENT.8.G.A.5

Use informal arguments to establish facts about the angle sum and exterior angle of triangles, about the angles created when parallel lines are cut by a transversal, and the angle-angle criterion for similarity of triangles

What's Included

It contains the following resources:

24 Mixed Review Questions concerning Angle Relationships in Similar Triangles, Exterior Angles, and Parallel Lines & Transversals

in TWO formats:

1) Scavenger Hunt (All questions multiple choice)

2) Task Cards (Some questions multiple choice, some short answer)

Also included are files without answer keys best for posting online in Google Classroom or similar platforms for students to view the questions without printing.
