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.
The NEVER cross each other
The answer would be parallel lines these lines never meet or cross each other.

All sides are connected with no open gaps, sides do not intersect or cross over 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.
They are closed plane figures bounded by straight lines that do not cross each other.
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.
The NEVER cross each other
The answer would be parallel lines these lines never meet or cross each other.
