When a polygon has an even number of sides, each side has an opposite side, and each vertex likewise has an opposite vertex.
When a polygon has an odd number of sides, each side has an opposite vertex.
The opposite side (or opposite vertex) to a given side (or vertex) is that side (or vertex) which has the same number of sides between it and the side (or vertex) in question.
