How to draw a 15 degrees using only compass?

draw 2 lines perpendicular to each other, bisect it u will get 45 degrees, then wait? how u divide it by 3 to get 15? fuck.. i give up..

hmmm, after a while, my right angle triangle embedded in my head gave me a hint, 30 degree angle is the inverse sine of 0.5 which is 30 degrees. A right angle triangle with a 30 degree angle has the hypotenuse twice as long as the leg opposite the near leg.

so, draw 2 lines perpendicular to each other then draw the leg opposite the 30 degree angle. draw the hypotenuse twice as long, that makes a 30 degree angle

Bisect that angle and tadaa 15 degrees, but when I just realize its that easy, I'm already sick of drawing my technical drawing assignment, wasted fucking 30 mins thinking of how to draw it when i have no protractor and other geometry sets but a compass with me.

so the solution is, sleep now and get a fucking protractor tomorrow and draw that 15 degree angle and get the drawing done on break, which leaves me plenty of time to dimension it at night.

DUE wednesday... xD

friday got a calculus test..

next friday got a materials test..

then that stupid lan subject BM has tonnes of assignments

plus the materials class got a group assignment which i don't even know who the hell are my group members which due 2 weeks later.

well, that's what I call heat and excitement non stop till the end of semester!
