Angle Relationships Practice

What you get

• Warm-up prompts that review linear pair and vertical angle theorems before introducing transversals.
• Guided practice with labeled diagrams, workspace for algebraic angle solving, and reasoning sentence frames.
• Application problems using real-world contexts like architectural trusses and road design.

Teaching moves

• Launch with quick whiteboard polls to diagnose which angle relationships need extra modeling.
• Assign peer checking roles where one student justifies each step while the partner verifies algebra.
• Use the final application page as a station during review week or as an exit ticket.

Standards focus

• CCSS G.CO.C.9 and G.CO.C.10 for proving and applying angle relationships in parallel lines and triangles.
• Mathematical Practice 3 for constructing viable arguments about congruent angle pairs.
