Answer 19

btw I don't know if BGM and AGD are similar, can't be sure ...but having an angle common must make triangle similar right?

Answer 20

BGM ~ DGA (AAA)

Answer 21

Yes, that is the correct approach. Btw @Callisto testing AA is sufficient for similarity.

Answer 22

I know... but my teacher asked us to prove the 3rd angle also.

Answer 23

What if two triangles have a common side? I suck at elementary geometry :/

Answer 24

You have to show steps in exam?
