Quote:Triangle- A closed figure consisting of three line segments linked end-to-end. A 3-sided polygon.

that "triangle" as you call it certainly is not comprised of coplanar line segments... and you can even tell the lines aren't strait yet you seriously think it's a triangle? it resembles a triangle, which is why they call it one, but it is not a triangle.
Maybe you should re-read the definition of coplanar
Quote:In geometry, a set of points in space is coplanar if all the points lie in the same geometric plane. For example, three distinct points are always coplanar; but a fourth point or more added in space can exist in another plane, or, incoplanarly.
