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 found that contains given three points?
3 points
How many different lines are determined by two points?
In classical or Euclidean plane geometry two points defines exactly one line. On a sphere two points can define infinitely many lines only one of which will represent the shortest distance between the points. On other curved surfaces, or in non-Euclidean geometries, the number of lines determined by two points can vary. Even in the Euclidean plane, two points determine infinitely many lines that are not straight!
How many lines can you draw through two points?
one
How many lines can pass through 2 points?
1
How many lines can be drawn through two fixed points?
In Euclidian or plane geometry, there can be only one line through two fixed points. Lines cannot actually be drawn; if you see it it is not a geometric line. If the points are on a curved surface as in a geometry that is non-Euclidian, then there can be infinitely many lines connecting two points.
How many weight watcher points are rainbow drops?
how many lines are in a rainbow
How did the massacre at mystic change US?
The Massacre at Mystic changed the US because it was the vision of what would happen to Native Americans for many years to come.
For 3 non collinear points how many straight lines can be drawn?
3 lines and one plane
How many lines are determined by 13 points no 3 of which are collinear?
There are 13*12/2 = 78 lines.
How many rotational lines of symmetry does an equilateral triangle have?
Rotational symmetry is based on points of rotation not lines
