For each pair of triangles below, determine if the triangles are congruent, similar but not congruent, or if their relationship cannot be determined from the information given. If they are congruent, organize your reasoning into a flowchart. Remember that the triangles may not be drawn to scale.

Use the triangle congruence conditions.

  1. Triangle A, B, C and triangle D, E, F. Angle B is 120 degrees and angle C is 35 degrees. Angle E is 120 degrees and angle F is 35 degrees.

    Similar by ~.

  1. Triangle M, N, O and triangle P, Q, R. Side N, O is 2 and side Q, R is 2. Angle O is 80 degrees and angle M is 15 degrees. Angle P is 15 degrees and angle Q is 80 degrees.


  1. Triangle G, H, I, and triangle J, K, L. Side H, I is 8 and side G, I is 5. Angle I is 62 degrees. Side J, K is 5 and side J, L is 8. Angle K is 62 degrees.

    Are the corresponding parts in the correct places?
