Lines of Longitude meet/intersect at the North & South Poles ONLY.
This is true. If three straight lines are drawn, they can only intersect at two points. That is, each line will only intersect with another once.
Perpendicular lines intersect at one point only.
No, only three lines can intersect at a single point.
Lines in a plane can intersect at only one point.
Assuming that the none of the lines are parallel, they can intersect (pairwise) at three points. Otherwise, the question is tautological.
A point can be intersected by infinitely many lines. Two points intersect in only one line. Three points either intersect in a line or not at all. This is only considering two dimensions.
Yes, but only if they are mutually coincident.
Two straight lines, whether they're in the same or different planes, must intersect at either one point or else at no points.
In plane Euclidean geometry, only onle line can go through two distinct points.
Any two lines can only have one point of intersection. Unless they are parallel, in which case they do not intersect at all. If they are the same line, then they intersect at an infinite number of points.
Yes. The easiest example is to take two parallel lines and use the third line as a transversal.
