How do you guys approach this type of AR problem? I get them wrong every time and its really frustrating.


Thank you!

lol I'd like to know as well . Throw in some obtuse angles, flip the orientation and I can't differentiate them at all.

I used to approach these problems by drawing an imaginary straight line at the angles and seeing which has more "white space" between the imaginary line and each leg of the angle. There's also the hill method when you take one leg of both angles as your "horizontal floor" and consider which second leg is steeper to climb. Tbh it's difficult to see a 3 degree difference at your stage of training. That's something even I'm struggling with in dental school as we enter prosthodontics. Keep at these practice problems to train your brain to be comfortable analyzing degrees from different angles.

On the exam, you should look at the answer choices to help with process of elimination. Guess to the best of your ability and move on.


I usually do the hill method but for this problem i dont know which leg would be my floor since theyre all rotated differently
 
Comparing 1 and 2 - I establish the bottom leg in 1 and the bottom leg in 2 as my floors by tilting my head a little to get the floors as horizontal as possible to my line of sight. Then I analyze one leg for steepness, quickly move on to the other angle, re-establish my horizontal floor perspective and analyze the other leg. In my mind as I'm looking at each angle, I draw out the path it takes, going from one end of the "horizontal leg" to the other leg to get a sense of which angle opens wider. Same idea comparing 3 and 4. It takes some patience and a lot of practice.


thank you! ill try it out, but can I tilt my head during the exam?
 
i have found rapid eye to be pretty much useless for obtuse angles. Illumident's drawing of a line is how i approached it and it essentially transforms the obtuse angle into an acute one. This is how i looked at it.
