a semi circle.. (:
It has 2 sides - one straight and one curved.
If you are referring to a shape, then a semi-circle would be the most likely shape that contains one straight side and one curved. Take a look at a protractor, it's a semi-circle.
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

Two: a straight line and a curved line.

Irregular shape is the term given to an object which has 1 flat side, 1 curved side, no corners but has curved edges.
One side and no angles. Unless you define a side as having to be straight line, then it is no sides. If a side can be a curved line by definition, then the number of sides is not an infinite number. If a side can have any curve then a circle has one side which connects into itself.
