I'd try and stay away from doing it free hand, it could end up looking bad. If you can't get a projector try the way I suggested with the printing, it's not as bad as it sounds. Make sure the lines of the triangle are straight using a large ruler or a straight piece of wood. do the top line first making sure it is straight with a spirit level and measure all lines and angles so it doesn't go wonky. Also use masking tape to get a good crisp straight line.
If you do want to do it freehand, Pm me and I'll let you know the best way to do it.
