the north pole is the place where the 2 0 degree lines intersect
Skew lines
radius
perpendicular
skew lines
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
Intersection or Intersecting Lines
They are called skew lines.
