Help with deductive geometry hw

Hey everyone

I was wondering if anyone could help out with my deductive geometry home work, Ive done about 3/4 of it and just need help with the last 4 questions. I need to prove/justify each step as well. Thank you all so much in advance I've got an exam on this stuff in two week and really need help on understanding it.

Here are the links:
