About this worksheet

What students practice

  • Students use triangle sums and exterior-angle relationships to find and justify angle measures.
  • Students explain angle relationships formed by parallel lines and a transversal.
  • Students use angle-angle similarity to compare triangles and identify corresponding vertices.

How to use

Use after introducing triangle angle arguments and AA similarity. Have students show angle equations on separate paper and discuss the final claim.

Curriculum

Common Core standard covered

8.G.A.5

Give informal arguments about triangle angle sums, exterior angles, angles from parallel lines cut by a transversal, and angle-angle similarity.
