mathmale · Answer

The first thing I would do here would be to calculate the measure of Angle C.

mathmale · Answer

Yes indeed.  Therefore, angles A and C equal angles A' and C'     What does that tell you?

mathmale · Answer

The angles are similar and congruent, but the line segments AC and A'C' are not congruent.
What does the problem call for?  Review the problem and then see if you can answer it using the fact that Angle C' is 83 degrees.

mathmale · Answer

What is the measure of Angle B?  Why?

mathmale · Answer

Yes.  B would be 56 degrees.  Now, are those 2 triangles similar or not?  Justify your answer.

mathmale · Answer

You might want to review the definition of "similar."

mathmale · Answer

All of the conditions for similarity between the 2 triangles have been met, and thus they are similar.  What did you learn from doing this problem?
