Can two lines be coplanar always?
No. Skew lines are never coplanar. Stand in a cuboid room and consider the line where the opposite wall and the floor meet. Consider also the line where the walls behind you and to your right meet. Those two lines are not coplanar.
Two lines in the same plane that never meet?
Two coplanar (in the same plane) lines that don't meet are parallel.
Do non-coplanar forces can be concurrent forces?
¢The forces, which meet at one point, but their lines of action do not lie on the same plane, are known as non-coplanar concurrent forces.
What is describes lines that meet at right angles?
They meet perpendicularly. Perpendicular lines meet at a 90 degrees angle.
What are coplanar angles?
mama mo * * * * * An angle is formed when 2 lines meet at a point: the vertex. Two lines which meet in this way always define a plane. Coplanar angle are two or more angles which are all in the same plane. In 3-dimensional space, it is easy to find angles which are not coplanar. For example, in a cuboid room, the angle formed by the lines where the floor meets two adjacent walls, and where the ceiling meets the same two walls are not coplanar: the angles lie in parallel planes. The same first angle and the angle formed where the ceiling meets another pair of walls are neither coplanar nor in parallel planes: they are in skew planes.

Two lines in the same plane that never meet?
Two coplanar (in the same plane) lines that don't meet are parallel.
Why Don't Parallel Lines Ever Meet?
Because they never move closer to each other; they are always the exact same distance apart. They don't meet by definition. If the lines in question ever met you would have to come up with a new word to describe them. Basically, the word parallel is an agreement between everybody practicing Euclidian geometry. We agree to call two lines parallel if they meet the following two criteria: 1. A plane exists on which both lines can exist 2. They never meet If only #1 is met the lines are called "coplanar" (actually it can be shown that any two lines that do meet must be coplanar) If only #2 is met the lines are called "skew"
Do non-coplanar forces can be concurrent forces?
¢The forces, which meet at one point, but their lines of action do not lie on the same plane, are known as non-coplanar concurrent forces.
Do intersecting lines never meet?
No but parallel lines never meet
Two lines that never meet?
Parallel Lines will never meet
What line is coplanar and meet at a point?
One line cannot be coplanar, and there is nothing for it to meet.
Coplanar lines with no point in common?
Think of a plane as being a sheet of paper that goes on forever in all four directions. Coplanar means that they are on the same plane. Think of how you would draw two lines (which go on forever in two directions) on that sheet of paper so that they would never meet each other (not have a point in common)--you would draw two parallel lines.
What is describes lines that meet at right angles?
They meet perpendicularly. Perpendicular lines meet at a 90 degrees angle.
Are three lines always coplanar?
No. Normally, two lines will uniquely identify a plane, unless they happen to be parallel. If you add a third line, it will usually not be in the same plane.* * * * *Not quite. Two lines that meet will uniquely identify a plane. But you can have lines that are neither coplanar nor parallel.For example, consider a cube and think of the line defined by the front bottom and one of the back verticals. Neither parallel, nor coplanar.
Do parallel lines meet at a 30 dregrese angle?
Lines that meet are not parallel, and parallel lines never meet.
Which lines will never meet?
Parallel lines
