Is a circle a polygon with curved sides?
No, all polygons have straight lines. All lines are straight
Is a circle a regular polygon?
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.
How many curved lines does a oval have?
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.
Can a circle be made of straight lines?
No. A circle has no straight lines. You can approximate circles with very small straight lines (that's how a computer draws circles) but mathematically, no.
What is an arc in a circle?
a curved line that is part of the circumference of a circle
