If they are in the same plane, then they share a common plane. Did you mean to say common point. If that's the case where they are in the same plane, but do not share a common point, then they are parallel lines.
Co-planar means being in the same plane.
If you mean the plural of plane, it is planes. If you mean the spelling of another word that is pronounced the same way, it is plain.
coplanar lines just mean that two lines are on the same plane. If they do not intersect, that means that they are on the same plane and are parallel to one another
Coplanar means on the same plane. As co-linear means on the same line.
The correct phrase is "On the same plane". A plane in this case being a level of development, existence, or achievement.
If they are in the same plane, then they share a common plane. Did you mean to say common point. If that's the case where they are in the same plane, but do not share a common point, then they are parallel lines.
Co-planar means being in the same plane.
not on the same plane, or flat surface. Most of the planets are in the same plane, but Pluto is on an angle so it is non-planar
If you mean the plural of plane, it is planes. If you mean the spelling of another word that is pronounced the same way, it is plain.
Lines or points lying on the same plane
coplanar lines just mean that two lines are on the same plane. If they do not intersect, that means that they are on the same plane and are parallel to one another
Coplanar means on the same plane. As co-linear means on the same line.
They can be, but not necessarily. If two lines in the same plane never intersect, they are parallel. Though, two lines can exist in the same plane without being parallel. Ie, two lines that intersect at a 90 degree angle are perpendicular. Most lines in a plane aren't parallel.
Yes, but the phrase is "on the same plane". In this case, "plane" does not mean aircraft, but flat level or surface, and the phrase means "on the same level of existance, consciousness or development".
Naughty and mean are not the same. A better synonym for mean is cruel. A synonym for naughty is mischievous.
Intersecting lines are those that lie in the same plane and cross each other at some point. Unless they are parallel, lines in the same plane always cross.
