a decagon i believe has either 5 or 20 opposite sides

* * * * *

A decagon has 10 sides so I cannot see how it could have 20 opposite sides. It has 5 pairs of opposite sides but this does not mean that these opposite sides face each other. In an irregular decagon it is quite possible for opposite sides to be at right angles or at any angle to each other.
