Ok to help you guys this is what I do for angles that gets me 11-12 each time on angles:
First practice making right angles with this:
http://woodgears.ca/eyeball/index.html
Play this game after a week you should be getting used to creating a 90 degree angle with ease and it gets you familiar with the pixels of the computer screen
General rules:
- Use the rapid eye glance technique to deduce which one is bigger, eliminate choices for example:
A. 4312
B. 3124
C. 4132
D. 3412
1) I would immediately look at 3 and 4 to deduce my angles down to the lowest # of choices
2) I would also look for patterns hidden within the answer choices because the real DAT doesn't have always clear cut answer choices like stated above. For example:
A. 1342
B. 2341
C. 3124
D. 1324
It seems like 1 and 2 is the correct order of pattern in A, C, and D. I would look at those 2 angles and determine which one is right. I would eliminate B. Then I would look at 3 and 1 between a, c, and d. In A and D you can see 1 < 3 and in C: 3 < 1. I would determine the answer and deduce my choices down, if there is still deduction to be left over between A and D which is just 2 and 4, compare those angles and you have your answer.
All of this process should take you no more than 45 secs max. I know you are probably like this is a long process but the harder you make it for yourself the easier the real thing will be.
But what if the rapid glance technique doesn't work and after looking at the two angles consecutively you can't figure out which one is bigger or not? You just got yourself an angle gods question:
Acute angles:
A) Wine technique - I imagine I pour wine and because I am sophisticated I keep it to certain levels in each cup. I precisely pour wine in each angle to the same height in each glass. Whichever glass has the most wine I choose it.
B) Lasers technique (Most helpful) - Where I imagine the base of the HQ is at the base of the angle where I want to shoot the most lasers out of (Lupe Fiasco shoot out). The more lasers I can shoot and in more directions the better. This way I am only concentrating at the base of the angle because I gotta protect my HQ/base
C) Hill technique - you have to have angles that are on the same level for this one or you gotta tilt your head - Imagine you are riding down your bike and want to estimate your velocity

90 degree angles:
This technique is for the angles that are close to 90 degrees either if they are acute or obtuse. This is where the eyeballing game comes in handy. You have to be good at estimating your 90 degree angles because you are going to use it as a reference point to figure out which one is smaller or bigger?

I especially used free hand to show you that even with fluctuations of your 90 degree angles could give you help in deducing which one is the right answer. You can even use your mouse to draw that imaginary line for the 90 degree line.
Obtuse angles (I mean obtuse)
Laptop technique:
Pretty self explanatory

But when that doesn't work:
180 degree line
I imagine a 180 degree line if you push the base of the angle and see how much of a angle is left over with the leg of the angle and try to imagine lasers again
The point is you should have techniques for every kind of angle they could throw you. Since these are the only angles they could throw you and the only way the ADA can make it harder for you and which they have done over the years is do smaller and smaller differences between angles, you have to keep practicing.
Last advice get royal flush of crack dat pat and turn down the angle difference (new feature I think) to 2 degrees and keep practicing with those day and night. And the regular angle deduction will seem easy. All these techniques get used in those because those answer sets are not just the ohh 3 is bigger than 4 that eliminates 2 of my answers because 4 is the biggest.
Review:
1) Look at answer choices
2) Look at pattern of answers
3) Determine which angles you have to focus on
4) Rapid glance technique (if don't work after 3 cycles of glances then go on to step 5)
5) Usage of different angle measurement techniques based on the angles given.
Other than that angle gods control your fate
I hope this helps and I am going to sleep
P.S. those acute angles are the same ones that I was asking about in the other thread
