perpendicular
Perpendicular lines intersect each other at 90 degrees which is a right angle.
if the two line intersect at 90 degree then these are called perpendicular lines
Skew lines
right angle
They are called perpendicular.
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.
Exterior angles
radius
skew lines
the north pole is the place where the 2 0 degree lines intersect
They're either parallel lines or skew lines.
An angle is formed where two lines meet. Parallel lines do not meet. Therefore they do not form an angle. So there is no angle to have a name. So no name.
