The triangular slit that opens and closes during talking is called the glottis. It is the space between the vocal folds (cords) in the larynx and plays a crucial role in voice production by controlling airflow and sound modulation. When the vocal folds come together, the glottis closes, and when they are apart, it opens, allowing air to pass and produce sound.
The triangular structure for rapid backward movement is known as the "triangular sail" or "tri-sail." This design is often used in sailing vessels to enhance maneuverability and speed when sailing downwind or in reverse. Its shape allows for efficient airflow, providing better control and stability during rapid backward movement.
One prominent African crop exported during the triangular trade was tobacco. Grown in various regions, particularly in West Africa, tobacco was highly sought after in Europe and the Americas. The triangular trade facilitated the exchange of tobacco for manufactured goods and enslaved people, significantly impacting the economies of the involved regions.
The triangular passage, also known as the triangular trade route, refers to a historical trade network that connected Europe, Africa, and the Americas during the 16th to 19th centuries. This route facilitated the exchange of goods, such as textiles and rum from Europe, enslaved people from Africa, and raw materials like sugar, tobacco, and cotton from the Americas. The triangular passage played a significant role in the development of the transatlantic slave trade and had lasting economic and social impacts on all three regions involved.

It's probably no more than a personal preference. Talking can be a distraction when you need to concentrate. Don't worry about it.
It's called the 'epiglottis'.

The knee joint is an example of a body joint that opens and closes as it flexes and extends during movement.
The flap that closes off the larynx is called the epiglottis. It is a flexible, leaf-shaped structure that prevents food and liquids from entering the airway during swallowing, directing them towards the esophagus instead. This protective mechanism helps to prevent choking and aspiration.
