The number of triangles that can be formed by choosing the vefrom a set of 12 points,seven of which lie on the same straight line,are:

The number of parallelograms that can be formed from a set of 5 parallel lines intersecting another set of 4 parallel lines is

Consider 2 parallel lines PQ and RS. Line PQ has two points A and B while RS has 8 points.Number of triangles that can be formed taking these 10 points as vertices of triangle is

Given 1 and 2 are two parallel lines. How many triangles can be formed with 12 points taking on 1 and 6 points on 2?
