If no pair of lines is parallel and if each pairwise intersection is distinct, there will be 10 points of intersection.
5 x 5 equels 10
the parallel lines never intercept so they do not have any common points.
A regular pentagon has 10 lines of symmetry. This counts the five points of the pentagon as well as the midpoints of each side.
There are 91 lines.
10 lines, but only if no three of them are collinear.
there are 6 lines can pass through 4 noncollinear points.
10
There are 20 common points.
3 points
points : infinite lines : 4 vertices : 4
If only 7 are colinear, then the question implies the lines need not go through every point. In that case there is an infinity of lines for each point.
