What does the Pentagon shape mean?
A pentagon is a geometric two-dimensional shape with five sides and five angles. The definition of pentagon shape is derived from the Greek word as “Penta” denotes five, and “gon” denotes angle. The pentagon is a 5-sided polygon. The home plate seen on a baseball field is an example of a pentagon shape.
Does a Pentagon have a meaning?

Why does a pentagon have 540 degrees?
Why is this? This is because you can make any pentagon with three triangles. Remember, the 3 angles of any triangle always add up to 180 degrees. So if you have three triangles making up your pentagon, then your angles will always add up to 540 degrees (3 * 180 degrees).
Why does the Pentagon have 5 sides?
