If you see on the word trigon, you may find, that the "γωνος" part also means side, line segment.

The historical meaning of the Greek word γωνία, in my opinion, is not a crooked line but a cracked (stem-broken) line. The Greek term πολυγωνική, as I see it, doesn't mean that the line is crooked but it is cracked.
