A polygon is defined as "a plane figure that is bounded by a finite chain of straight line segments closing in a loop to form a closed chain or circuit"... So - Yes.
Any Polygon can be a regular figure, if the figure has all straight sides and edges, with all the same length. If the decagon had all straight edges, sides, and same lengths of sides, it would be a regular figure. Otherwise, it would not, and would be an irregular Decagon. * * * * * That is not a correct answer. Any polygon, by definition MUST have all straight sides (which are the same as edges). What makes a polygon regular is that all the sides are the same length AND that all the interior angles are the same measure. Both these conditions must be met.
NO, a circle is not a polygon. A polygon is composed of a finite set of straight line segments, and a circle has NO straight line segments.
A semicircle is an example of a figure with one straight line. It is a circle that has been split along the diameter.
A straight line of finite length can be a side in a parallelogram.
The radius is a cord, is it not?
A polygon is a plane figure bounded by a finite number of straight lines. To enclose an area then a minimum of three straight lines are required. All triangles, not just isosceles triangles, are polygons.
A rhombus is a closed 2-dimensional figure with four straight sides of equal length.
A line segment is a smaller section of a straight line and has a finite length and distinctively identified on a drawing by the points at the both ends

A line segment.
A line is of infinite length, a segment is of finite length.
Yes
The formula for a rhombus is as follows: "a closed 2-dimensional figure with four straight sides of equal length".
A polygon is defined as "a plane figure that is bounded by a finite chain of straight line segments closing in a loop to form a closed chain or circuit"... So - Yes.
A polygon is any plane figure with a finite amount of straight line segments. Some examples of polygons without parallel sides would be a triangle, a star and a pentagon.
