If the line is straight, then only one line may connect two points.
To construct an inscribed square within a circle, four lines will be drawn. These lines are the sides of the square, which connect the points where the square touches the circle. Additionally, if you include the lines from the center of the circle to the vertices of the square, you would draw four more lines, totaling eight lines. However, strictly for the square itself, only four lines are necessary.
There are 91 lines.
there are 6 lines can pass through 4 noncollinear points.
There are 20 common points.

the parallel lines never intercept so they do not have any common points.
There are 91 lines.
there are 6 lines can pass through 4 noncollinear points.
There are 20 common points.
Intersecting lines have exactly one point in common, which is the point of intersection. At this point, the two lines cross each other. If lines are parallel, they do not intersect and have no points in common. Lines that are coincident lie on top of each other and share infinitely many points.

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.
If no pair of lines is parallel and if each pairwise intersection is distinct, there will be 499500 points of intersection.
