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 coplanar angles that have a common side and a common vertex but no common interior points?
adjacent planes
What is a coplanar point and non coplanar point?
Coplanar means "on the same plane", so we can imagine that non coplanar means "not on the same plane".For example, if you draw a square and point on a piece of paper, the two objects are coplanar. However, if we were to add depth and the objects were a distance apart, they are said to be non coplanar.
Is 3 points coplanar colinear?
3 coplanar points may or may not be collinear. 3 collinear points must be coplanar.
What is coplanar lines?
coplanar lines are lines lying on the same plan.
What is an example of coplanar points?
Three balls on a table are three coplanar points.
Are vertical angles coplanar?
Yes, the opposite rays of vertical angles are always coplanar, so the angles are as well.
What angles do not intersect and are coplanar?
Angles that are separated by a distance. For example, any two angles of any polygon do not intersect and they are coplanar.
Can three coplanar angles have a common side?
NO
How many angles can be made by 3 coplanar points?
3
Two coplanar angles with a common side?
adjacent planes
Two 60 degree angles?
make 120° when they are coplanar.
Two lines which intersect to form right angles?
...must be coplanar.
When wo coplanar lines are cut by a transversal two angles that are in similar positions on the same side of the transversal are called?
corresponding angles
How many Alternate interior angles are formed when the transversal cuts two coplanar lines?
Two pairs of alternate opposite angles
When two coplanar lines are cut by transversal the angles between the two lines on opposite sides of the transversal are called what?
Alternate Interior Angles
Two coplanar angles that have a common side and a common vertex but no common interior points?
adjacent planes
How many pairs of vertical angles are formed by 3 coplanar lines intersecting at one point?
Eight.
