Question

Are the following triangles similar? Justify your answer.

This is what I have so far...
angle D = angle G
angle E = angle H
angle F = angle I
Therefore all corresponding angles are congruent.

However, I am not sure if I can prove that they are similar with proportions. I know that if I did, I would set it up to look like 6/10=4.5/HI and 6/10=DF/12.5
So, can I prove they are similar with this method?

Answer 1

Yes by Angle Angle (A-A) or Angle Angle Angle (A-A-A) property ΔDEF~ ΔGH

Answer 2

Thanks!
