a. 1 b. 4 c.2 d. Infinite

The number of circles that touches all the three lines x+y-1=0, x-y-1=0 and y+1=0 is

The number of circles that touch all the straight lines x+y-4=0, x-y+2=0 and y=2 , is

There are 10 points in a plane and 4 of them are collinear.The number of straight lines joining any two of them is 4 b.40 c.38 d.39

If n lines are drawn in a plane such that no two of them are parallel and no three of them are concurrent,such that these lines divide the planein 67 parts,then find number of different points at which these lines will cut.

If 20 lines are drawn in a plane such that no two of them are parallel and so three are concurrent,in how many points will they intersect each other?

Number of circles that can be drawn through three non-collinear points is 1 (b) 0 (c) 2 (d) 3

There are five points A,B,C,D and E. no three points are collinear and no four are concyclic. If the line AB intersects of the circles drawn through the five points. The number of points of intersection on the line apart from A and B is

If there are nine straight lines of which five are concurrent at a point and the other four are concurrent at another point and no two of these nine lines are parallel, then the number of points of intersection is equal to

n lines are drawn in a plane such that no two of them are parallel and no three of them are concurrent.The number of different points at which these lines will cut is a.sum_(k=1)^(n-1)k b.n(n-1) c.n^(2) d.none of these
