Two Scalars that go in opposite directions
One scalar and one vector!
The answer is given on the following page.
One dimension has only one axis of possibilities. Motion in one dimension is motion on straight line. Two dimensions is motion on a plane. Two axes meet at right angles and extend in both directions. A point can be located anywhere that can be described as two points in this plane.
Two-dimensional.

No. The rules of two dimensional geometry can only be used for two dimensional geometry. You can take the basic principles of two dimensional geometry and alter them slightly to be able to apply to three dimensional solids

Two-dimensional motion
A motion along straight line is called rectilinear motion. In general, it need not be one - dimensional; it can take place in a two dimensional plane or in three dimensional space. But, it is always possible that rectilinear motion be treated as one dimensional motion, by suitably orienting axes of the coordinate system.
