Any polygon has the same number of vertices as it does sides; this is a constant that never changes, no matter how many lines are introduced into a polygonal shape.

A collinear vertice refers to a set of points that lie on the same straight line.

Triangles are classified by the length of their sides and by the interior angles of the corners.
