RealiseNothing Jun 18, 2012 Send it then. It reminds me of a Q7 in a past 3U HSC paper. It was a parametrics question that would of been so tedious to do using parametrics, but you could use circle geo and do it in like 3 lines.

RealiseNothing Jun 18, 2012 It's just circle geo. A right angle triangle can be inscribed in a circle such that the hypotenuse is the diameter and mid point is the centre. Then the midpoint to the opposite corner is just the radius.
