the Spanish armada set sail on 12th July 1588
No one can say who, where or when the first sail was made. Consequently its shape is not know either.
The best shape of a sail depends on the sailing conditions and intended use. Generally, a curved, full sail shape is ideal for maximizing lift and power in lighter winds, while a flatter sail shape is better for stronger winds to reduce heeling and maintain control. Ultimately, the optimal sail shape balances aerodynamic performance with the specific requirements of the sailing environment.
No
the shape dose effect it.

The name pretty much specifies itself, a sail in the shape of a triangle. lol.
"Asymmetrical" is a description of the shape of the perimeter (outline) of the sail. It just means that it is not symmetrical.
