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 pentagon has five lines of symmetry. Each line of symmetry passes through a vertex and the midpoint of the opposite side, dividing the pentagon into two equal halves. The lines of symmetry for a regular pentagon are evenly spaced at 72-degree angles from each other.
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.
