Hey Diane8611.

The answers to the first ones are all just definitions. When you say a "co" it means that the things have a particular "thing" in common. So when you see "co-planar" it means that the plane they lie on is "common" to all points.

So with this hint can you guess what the other "co" terms relate to?
