For # 1-6 - please leave your answer in there if it shows up wrong. I've tried to put all possible combinations of answers in, but I am sure I missed one. I will look through these by hand and give you feedback if it is incorrect. Please be sure you watch this video for answer format: Video #2 - Segments vs. Lines
Also, points (since ch 1) are named with capital letters. You need to use capital letters. It is not line ab, it is line AB.
