A quadrangle is any shape which has 4 angles. In order for an angle to exist, there needs to be two lines meeting at a point. If the shape is a polygon (a closed 2d shape) then 4 angles means it must also have 4 sides. Thus a quadrangle with only one side would be impossible.
A shape cannot have only one side because it would not be closed. A shape must have at least three sides to be a closed figure (no "gaps")
A shape with three linear sides and one curved side can be drawn, but such a shape has no specific name.
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.

a line
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.
In geometry, the only shape that has one surface is a plane.
The Moon only seems to "change shape". We only see one side of the Moon from Earth. The variation in the amount of sunlight hitting that side of the Moon, as it orbits Earth, is why we see the apparent changes in shape. These changes are called "lunar phases".
Vesta is round and its radius is only one number unlike other asteroids which have more of an oblong shape -like a potato- and so their radius is expressed for the long side and the short side.
hectagon
A shape with one side
A shape with three linear sides and one curved side can be drawn, but such a shape has no specific name.
Parellelogram
No shape does. However, a line and/or line segment is "one-sided".
