What is triangular sail name?

A triangular sail is named because of its shape, which is triangular. It is a type of sail that is commonly found on smaller boats and is used for propulsion. Triangular sails are often mounted on a foremast and are used in conjunction with a mainsail to provide additional power to the boat. They are relatively easy to handle and are an efficient way to catch the wind and propel the boat. Triangular sails are also known as jibs, genoas, and foresails, depending on their size, shape, and position on the boat.
