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.
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 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.
