No. of possible Intersection Points between lines ,Circles

The maximum number of points of intersection of five lines and four circles is (A) 60 (B) 72 (C) 62 (D) none of these

The greatest possible number of points of intersection of 8 straight lines and 4 circles is:

TANGENT : Intersection point of line and Circle are Coincident.

If the two equal chords of a circle intersect : (i) inside (ii) on (iii) outside the circle, then show that the line segment joining the point of intersection to the centre of the circle will bisect the angle between the chords.
