WebJul 2, 2009 · The formula to compute the triangle area is : area = bh/2. where b is the base length and h is the height. We chose the segment AB to be the base so that h is the shortest distance from C, the circle center, to the line. Since the triangle area can also be computed by a vector dot product we can determine h.
