 Right Triangle Median, Altitude, Bisector (Site not responding. Last check: 20071009) 
  Suppose triangle ABC is a right triangle, shown inscribed in a circle with diameter AB and center M. The bisector of angle ACB is shown here in purple, along with the perpendicular bisector of AB. 
  Law of Sines  Given triangle ABC with opposite sides a, b, and c, a/(sin A) = b/(sin B) = c/(sin C) = the diameter of the circumscribed circle. 
  Triangle Trisection  If a point, P, on the median of triangle ABC is the isogonal conjugate of point Q, on the altitude of ABC, then ABC is a right triangle.
