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
Oh honey, that's an easy one. Another name for a right angle DEF is a 90-degree angle. It's like the perfect L shape, straight up and down, no funny business. So, go ahead and call it a 90-degree angle or a right angle, whatever floats your boat.
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.
