The 30-60-90 and isosceles triangle rules regarding side ratios are difficult for me to remember...
I did undergraduate and graduate school in engineering (7+years) thinking of triangles in terms of sines and cosines. Since the angles on the gmat are either 30, 45, 60, or 90, I can easily compute the sine or cosine of an angle in my head. It's 5x times faster for me to just take the sines and cosines of the angles in my head and work from there and I'm much more confident in my answer. As oppossed to when I use the triangle rule where I'm second guessing if I remembered the rule correctly or not and then I usually end up taking sines and cosines to check my answer anyways.
Are there any potential problems with me tossing out triangle side ratio rules from my memory? Or can I just stick with sines and cosines.
I know this must sound crazy to most people, but I've been doing it this way for so long and I also do it on a regular basis in my day-to-day job.
Any feedback is appreciated.
