Truly, a circle has no straight sides.
If you draw a shape with enough straight sides, it will look like a circle if you don't look too closely, but it will never be a circle.
None.
An arc has no straight sides because its part of the circumference of a circle
An ellipse.
A circle has no straight sides but if you mean a circle that has been divided into 5 equal sectors then the angle of each sector is 72 degrees subtended by each arc of the circle.
They are straight lines, part s of which form chords of the circle.
None.
yes it can be a circle has no straight sides, but is symmetrical
It has 2 sides - one straight and one curved.
None. An oval is a "squashed" circle.
No. A rhombus has four equal straight sides. A circle has no straight parts.
a circle
Two: a straight line and a curved line.
A circle is not a polygon because it doesn't have any straight sides.
An arc has no straight sides because its part of the circumference of a circle
An ellipse.
A circle does not have any pairs of parallel sides. In geometry, parallel sides are defined as sides that are always the same distance apart and will never intersect. Since a circle is a curved shape with no straight sides, it does not have any pairs of parallel sides.
Common shapes with less than 4 sides are triangles and circles ( but the circle has no straight sides).
