Pirates
Scouts
American colleges

Nepal is one.

Switzerland have a square flag, is a square a rectangle?

[Brentbaggie]

Nepal is one.

Denmark? My mate lives there and it’s more often flown as a long streamer-like triangle?

Switzerland have a square flag, is a square a rectangle?

No, it's a square.

All 3 have been mentioned.
