A regular polygon is a polygon whose sides are equal length and whose angles are all the same value. A non regular polygon is just the opposite of a regular polygon.
A segment connecting any two non-adjacent vertices in a polygon is called
Regular polygon is equilateral and equiangular. Irregular polygon is non-equilateral and non-equiangular.
A polygon is 2 dimensional shape whereas a non polygon can be 3 dimensional shape
Any polyhedrons such as a cube is a non polygon
A non regular or irregular polygon is a polygon whose sides are not all the same length
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.
A non equal sided polygon is called a quadrilateral, or quadrangle.
A convex polygon is one with no angle greater than 180 degrees. A non-convex polygon is one that is not without such an angle.
A polygon is convex if you can take any two points inside the polygon and connect them with a line segment that is completely contained by the polygon. A non-convex polygon is one which contains at least two points such that the line joining them does not lie entirely inside the polygon.

No. In a convex polygon the sum of the interior angles is (n-2)*180 deg where n is the number of interior angles. In a non-convex polygon this is not necessarily true.
A simple polygon that is not convex is called concave, non-convex or reentrant. A concave polygon will always have an interior angle with a measure that is greater than 180 degrees.
