if the two line intersect at 90 degree then these are called perpendicular lines
If the line intersect but not at a 90 degree (right) angle it is then called an intersecting line and where they met is called a point
the north pole is the place where the 2 0 degree lines intersect
Skew lines
perpendicular
radius
skew lines
They're either parallel lines or skew lines.
skew
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.
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.
