Problem 27 of 7
Decide whether triangles are similar from angle data One triangle has angles 60 and 80. The second triangle has angles 40 and 80.
Using a hint is okay. It just tells the trainer to give you a little more review.

identify equal corresponding angles.
Hidden until you reveal it.
AA similarity requires two pairs of corresponding congruent angles.
Enter your answer
Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Identify known congruent angle pairs.
2. Use third-angle theorem if two pairs are known.
3. Conclude similarity by AA or state insufficient evidence.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Similarity from only one angle pair in general.
