If none of the sides ever cross each other, there cannot be a closed plane figure.
A polygon.
A polygon would fit the given description.
A triangle cannot have two parallel sides. In order for a figure to be a triangle, it must be a closed figure with three sides and three angles. If two of the sides were parallel, there is no way the figure could be closed by only one other line.
A polygon with ends that don't meet is known as a "non-simple polygon" or more specifically, a "self-intersecting polygon." In these shapes, the sides cross over each other, resulting in segments that do not connect to form a closed figure. An example is a star shape, where the lines intersect but do not create a single, closed loop.

A polygon.
All sides are connected with no open gaps, sides do not intersect or cross over each other.

They are closed plane figures bounded by straight lines that do not cross each other.
A triangle cannot have two parallel sides. In order for a figure to be a triangle, it must be a closed figure with three sides and three angles. If two of the sides were parallel, there is no way the figure could be closed by only one other line.
No, parallel actually means that the lines will never touch or cross

parallelogram is a special kind of quadrilateral which, in turn, is a special kind of polygon and that is a closed planar figure.
