Q.
P is point lying outside a cicle. 3 lines are drawn from P to the cicle so that they intersect the circle at 6 points as shown in the figure.
P1, P2, P3 are points formed by intersections of tangents at A and B, C and D and E and F respectively.
P1, P2, P3 are always collinear
No relation possible for P1, P2, P3
P1, P2, P3 may be collinear
P1, P2, P3 cannot be collinear
Q.
What is the polar of the point (2, 3) with respect to the circle x2+y2 − 2x − 4y − 4 = 0
x + y = 10
x + y = 12
x -y = 6
x - y = 10
