What are binary ionic compounds made of?
Some molecules (not just ionic compounds) always tend to come in pairs. Aluminum oxide for example Al2O3 always comes in a pair Al4O6, the empty electron pairs on the Aluminum making attractive sites for the filled electron pairs on Oxygen to 'stick' to.
What are forces that always act in equal but opposite pairs?
If the equal and opposite forces are separated by a certain distance they are called as couple. If the equal and opposite forces are not seperated by a certain distance their resultant is zero as per Parallelogram Law of Vector Addition.

No, it does not.
Are all rectangles parallelogram?
Yes. Parallelograms have two pairs of opposite sides that are parallel. Rectangles also have two pairs of opposite sides that are parallel, which makes them parallelograms.
