(3) Let's draw 5 points which are collinear.

The number of circles that can be drawn out of 10 points of which 7 are collinear is

out of 18 points in a plane no three are in the same straight lines except five points which are collinear how many triangles can be formed by joining them?

The number of straight lines that can be formed by joning 20 points of which 4 are collinear is-

There are n points in a plane , of which no three are collinear expept m which are collinear. Find the number of triangles formed by joining the points.

There are 10 points in a plane of which 4 are collinear, Find the number of lines obtained from the pairs of these points.

There are 10 points in a plane of which 4 are collinear, find the number of triangles that can be formed from these points.

There are 15 points in a plane of which 4 points lie in one stright line and another 5 points lie in another straight line . The two lines are parallel and no three of the remaining 6 points are collinear . Find (a) the number of straight lines and (b) the number of trangles that can be formed by joining the 15 points .

There are n points in a plane of which m points are collinear. How many lines can be formed from these points ?

In a plane there are 10 points out of which no three are collinear except the four which lie on a straight line . By joining these 10 points how many straight lines.

4 points out of 8 points in a plane are collinear number of different quadrilateral that can be formed by joining them is
