By its very nature of being a triangle, and a 2D shape, a triangle cannot have four plane faces. However, a tetrahedron is a polyhedron made up of four triangular faces.
A 2D shape with 3,000,000 sides is called a myriagon. The prefix "myria-" denotes 10,000, so a myriagon has 10,000 sides. In geometric terms, a myriagon is a polygon with 3,000,000 sides, each of equal length and internal angles adding up to 180 degrees. It is a very rare and complex shape in mathematics.
There is no shape that is made up 3 sides that is not a triangle. Any shape that is made up of 3 sides is classified as a triangle no matter what shape or size it is.
because the airfoil shape makes tiny air molecules at the bottom slow down and the top speed up. The engine just pushes the plane.
