there are thirty (30) points. To double check, add 1+2+3+4... till 19. Since you are dropping one line for every point connected to all the other lines, you just add the numbers consecutavely from 1 to the second last number of your point. The reason you DON'T add the last number is because you can't connect one point with itself.

How many lines can be drawn out of 14 points on a plane with no 3 or more points collinear?
There are 91 lines.
How many lines passes through 4 points?
there are 6 lines can pass through 4 noncollinear points.
How many intersecting points occur when 4 parallel lines are perpendicular to 5 other lines?
There are 20 common points.
How many points is there in a square?
points : infinite lines : 4 vertices : 4
How many points can 2 lines have in common?
If the two lines are actually "on top of each other", they can have infinitely many points in common. If they are parallel, they have no points in common. If they are perpendicular, they have one point in common.
How many lines in a 20 point mystic rose?
190
How many points do parallel lines have in common?
the parallel lines never intercept so they do not have any common points.
How many lines can be drawn out of 14 points on a plane with no 3 or more points collinear?

How many points does 5 intersecting lines have?
If no pair of lines is parallel and if each pairwise intersection is distinct, there will be 10 points of intersection.
How many points do 4 intersecting lines have?
If no pair of lines is parallel and if each pairwise intersection is distinct, there will be 6 points of intersection.
