No, all polygons have straight lines. All lines are straight
No, a circle is not a regular polygon because it is not even a polygon.A polygon must have at least 3 sides and 3 angles (a circle has 1 side and has 0 angles), it has to be a closed shape, and it cannot have curved lines (circles are curved). Therefore, a circle is not a polygon. You *might* think that a circle is just made up of a gazillion squares, but no. It's simply just a curved shape.
An ellipse has just one. An oval can also refer to a circle that has been stretched by inserting two parallel straight sections - as in a running track. In such cases, it has two curved lines.
It could be a sector although that implies that (a) the curved side is part of a circle which it need not be and (b) that the two straight lines meet at the centre of the circle - again an assumption not justified by the requirements of the question.
curved
Lines that is curved. E.G the outline of a circle.
A curved shape does not have any straight lines. In a circle the line curves continually, meaning that the circle is a curved shape.
if you are drawing a circle with the help of circle tool in computer with paint, you will find that if you zoom it,the circle is made with small lines.

No, all polygons have straight lines. All lines are straight
A circles has no perpendicular lines. Perpendicular lines are two straight lines that join forming 90 degree angles. They are found in squares, rectangles, and right-angled triangles. A circle is made by one line that is not straight but is curved. If you drew a circle, rectangle, right-angled triangle, or cross in the circle, then the circle would contain perpendicular lines. But the circle itself would have no perpendicular lines.
Maybe only a circle and a oval. :P
A shape made up of line segments is a shape with straight lines, or a polygon. for example, a square has straight lines, or is made up of line segments. A circle is not in that category because it has no straight lines, they are curved.

It could be a stretched circle - a bit like an ellipse except that an ellipse does not have straight lines.
A polygon is a plane area bounded by straight lines. A circle consists of a curved line, not a straight line. Therefore a circle is not a polygon and conversely, no polygon can be a circle.
