This may be cheating I'm not sure*: I used my placard (the pink sheet they give you to take notes if you need) and held it up to extend the lines on some of the angles since it can be difficult to determine a 1 degree difference between angles if the lines are also very short. This probably only helps if you are an extremely visual learner and need to see an exaggerated angle to be able to decide between two that are very close.
*I only did this for the first few questions then stopped because I was worried I would get in trouble but I later asked (after completing the PAT because I was worried about asking a question and using up time) and the test administer said it was fine. Wish I'd done it for the whole test haha.
