[" 10.If the three points in a plane lies on a same "],[" straight line then they are called "]

If three or more points does not lie on the same straight line the points are called -

There are n points in a plane of which no three are in a straight line except 'm' which are all in a straight line. Then the number of different quadrilaterals, that can be formed with the given points as vertices, is

In a plane there are 10 points, no three are in same straight line except 4 points which are collinear, then the number of straight lines are

There are 15 points in a plane, no three of which are in the same straight line with the exception of 6, which are all in the same straight line. Find the number of i. straight lines formed, ii. number of triangles formed by joining these points.

In a plane there are 10 points, no three are in same straight line except 4 points which are collinear, then the number of triangles formed are

Out of 18 points in a plane, no three are in the same straight line except 5 point which are collinear. Find the number of lines that can be formed by joining them?

There are n points in a plane. Find the number of straight lines that can be obtained by joining points if a) no three points are collinear. b) p points are collinear.
