There are a couple of issues with this question. One, I have the movable triangle stacked directly on the stationary triangle, so the correct answer should be "Yes — And I've constructed a congruent triangle." Yet, it gives me an unhappy face. I tried the "No" answer, and it didn't like that either.

Second issue: Each time I went to check my answer, my browser would freeze up. Here's the error:

A script on this page may be busy, or it may have stopped responding. You can stop the script now, or you can continue to see if the script will complete.

Can you please look into the issues?

Thanks!
