a polygon must be a closed shape and has all straight lines
You have to think that if two are similar, the other must also be similar in order for it to be similar
A polygon must be a closed region without any curves or arches. so you cant close one or two segments to form a polygon
NO!!! The smallest polygon is 3 sided. it is a 'trigon' ( triangle).
A regular polygon has all its sides equal and all its angles equal. One consequence is that no angle can be reflex (between 180 and 360 degrees). A concave polygon, on the other hand, must have at least one angle that is a reflex angle. The line joining any two points inside any convex polygon (and that includes regular ones) must lie wholly within the polygon. In a concave polygon, it must be possible to find two point inside the polygon such that the line joining them crosses the boundaries of the polygon.
polygons must be closed and two lines cannot form a closed shape. There is not such thing as a two sided polygon.
No, polygons must have at least three sides.
If a polygon had 166 sides it would have 83 diagonals as each diagonal must join two vertices.
A non polygon is a shape that doesn't meet the requierments to be a polygon. In order to be a polygon, a shape must have no curved lines and must be a closed shape.

All sides must be equal in length and all angles must br equal in size
What polygon? Your asking "what are two names to describe a polygon" but haven't given a polygon...
No it is not a polygon, simply because it is a 3D shape. Yes it has all the other features but it is a 2D shape which is not one of a polygon's features.
