if the two line intersect at 90 degree then these are called perpendicular lines
the north pole is the place where the 2 0 degree lines intersect
Skew lines
radius
perpendicular
skew lines
When two lines meet to form a corner, it is called an "angle." The point where the two lines intersect is known as the "vertex" of the angle.
They're either parallel lines or skew lines.
An angle is a pair of lines (actually rays) that share a common endpoint.Lines that share a point are said to be intersecting.The point at which the intersect is called the intersection point.Intersecting lines are lines that share a common point.
Skew lines. However, it you alter the plane(s) these two lines can become parallel.
Perpendicular lines intersect each other at 90 degrees which is a right angle.
They only cross once because intersecting lines are only supposed to INTERSECT at one point, hence the name intersecting lines
