There are m points on the line AB and n points on the line AC, excluding the point A. Triangles are formed joining these points

There are m points on a straight line AB & n points on the line AC none of them being the point A. Tri- angles are formed with these points as vertices, when A is excluded (ii) A is included. The ratio of number of triangles in the two cases is

Find the mid points of the line segment joining the points .

Straight lines are drawn by joining m points on a straight line of n points on another line. Then excluding the given points, the number of point of intersections of the lines drawn is (no tow lines drawn are parallel and no these lines are concurrent). a. 4m n(m-1)(n-1) b. 1/2m n(m-1)(n-1) c. 1/2m^2n^2 d. 1/4m^2n^2

There are 10 points on a straight line AB and 8 on another straight line AC, none of them being A. How many triangles can be formed with these points as vertices?

There are 10 points on a plane of which no three points are collinear. If lines are formed joining these points, find the maximum points of intersection of these lines.
