Apr6 asked Find the area of region. Apr6 comment Area of triangle Please leave a comment if you are down voting Apr6 asked Area of triangle Apr6 comment Chord of contact of pair of tangents I found the equation of chord of contact which is $ax+by-1=0$, Then I took two points (1,2) and (2,0) on the given line. Then I got two chords. I solved them then I got one point. But I don't know how to prove the first part.
