the parallel lines never intercept so they do not have any common points.
Two lines intersect at one point. If in two dimensions, and they do not intersect they are parallel. The other option in two dimensions is they are the co-linear, that is they are the same line, in which case they intersect at all points.
how many sets of parallel lines are in a triangle
2 pairs of parallel lines
There are 2 sets of parallel lines.
A dodecahedron need not have any parallel lines.
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.
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.
None. Parallel lines do not intersect in Euclidean geometry.
If no pair of lines is parallel and if each pairwise intersection is distinct, there will be 499500 points of intersection.
If no pair of lines is parallel and if each pairwise intersection is distinct, there will be 10 points of intersection.
If no pair of lines is parallel and if each pairwise intersection is distinct, there will be 6 points of intersection.
Two lines intersect at one point. If in two dimensions, and they do not intersect they are parallel. The other option in two dimensions is they are the co-linear, that is they are the same line, in which case they intersect at all points.
A triangle can have no parallel lines.
A pentagon has no parallel lines.
it has too parallel lines!
A cone does not have any parallel lines
