no because a quadrilateral has straight sides if it were curved it wouldn't be a polygon because polygons must have straight sides
Yes
There is no specific name for such a shape.
A shape with three linear sides and one curved side can be drawn, but such a shape has no specific name.
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 two-dimensional shape with one curved side and four straight sides can be created, but there is not specific name for such a shape.

A shape with three linear sides and one curved side can be drawn, but such a shape has no specific name.
A major sector of a curve.
An arc has no straight sides because its part of the circumference of a 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.
The answer is: MAMA DAT SO HARD COME HELP MOOMY! I KNOW IT A CIRCLE
None A semicircle is the shape of a protractor (or half a pizza). It has one straight side and one longer curved edge.
