Normally just the one which is its circumference
A shape that has one straight side and one curved side is called a semicircle. A semicircle is a two-dimensional geometric shape that consists of half of a circle. The straight side is the diameter of the circle, while the curved side is the arc that forms half of the circle's circumference.
a semi circle.. (:
It has 2 sides - one straight and one curved.
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.
A circle is non-polygon. Meaning it has a curved side. A circle has no sides. It is non-regular.
If you have only one curved side, you could be a semi-circle or a crescent shape.

None normally unless its vertices touches the circumference inside circle.
A circle has one curved line and it is its circumference
One continuous curved edge
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.
Two: a straight line and a curved line.
The object you are describing is a circle. A circle has one continuous side with no corners, and its shape is defined by a curved line that is equidistant from a central point. It can also be referred to as a two-dimensional geometric figure.
Irregular shape is the term given to an object which has 1 flat side, 1 curved side, no corners but has curved edges.
