It’s not easy to tick me off… I don’t get angry often. But you mess with my wife, you mess with my kids; that’ll do it every time. Donald, you’re a sniveling coward and leave Heidi the hell alone.
Quadrilateral (Wikipedia)In geometry a quadrilateral is a four-sided polygon, having four edges (sides) and four corners (vertices). The word is derived from the Latin words quadri, a variant of four, and latus, meaning “side”. It is also called a tetragon, derived from greek “tetra” meaning “four” and “gon” meaning “corner” or “angle”, in analogy to other polygons (e.g. pentagon). Since “gon” means “angle”, it is analogously called a quadrangle, or 4-angle. A quadrilateral with vertices A, B, C and D is sometimes denoted as ABCD.
