What polygon? Your asking "what are two names to describe a polygon" but haven't given a polygon...
A polygon is a Two dimensional figure that is closed.
Although a polygon is usually thought of as a two-dimensional figure with at least three sides, there is nothing in the definition of a polygon that prohibits its use for the classification of a one-sided figure. A one-sided figure is known as a henagon or a monogon. A polygon, by definition, has as many vertices as it has sides, so a single-sided polygon would have to, in order to meet that criterion, curve in on itself so that the two ends of the side meet to form a vertex. In order for the polygon to not be curved, it would have to be made up of two straight lines (this figure is known as a digon). So no, a polygon cannot be a single straight line.
………………………… is a line segment that joins two vertexof a polygon but is not a side of the polygon.
there is no such thing as two-sided polygon.
Every polygon has two of its sides intersect.
A convex polygon.
A polygon is a two-dimensional figure. Therefore a cube is not a polygon.
a polygon in which any line segment connecting two points of the polygon has no part outside the polygon.

Do you mean a polygon? A polygon is a two-dimensional figure.
A concave polygon.
