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.
The name given to a set of coordinates is "coordinate system".
Skew lines
perpendicular
skew lines
the north pole is the place where the 2 0 degree lines intersect
They're either parallel lines or skew lines.
skew
if the two line intersect at 90 degree then these are called perpendicular lines
positive correlation
"Meridians" are the long lines on a globe or map that help pinpoint coordinates. Meridian lines are also called longitudinal lines.
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
The special name given to lines of latitude is "parallels," and the special name given to lines of longitude is "meridians." These lines form a grid system that helps in locating any point on the Earth's surface.
