A pair of parallel lines, an ellipse or a circle.
all right some body said that Ellipse Circle Oval but parallel shapes need to have lines so they are not parallel shapes so all i know that are not parallel is a diamond and a rhombus

A square has 2 pairs of opposite parallel lines.
There cannot be parallel lines in any [plane] triangles.

An ellipse has two lines of mirror symmetry: the line that includes the two foci of the ellipse and the perpendicular bisector of the segment of that line between the two foci.
None; an ellipse is a smooth curve, not a line.
An example of parallel lines are the two rails of a railway track, rails which never meet. An oval is a line or shape that has no parallel lines.

An ellipse has just one. An oval can also refer to a circle that has been stretched by inserting two parallel straight sections - as in a running track. In such cases, it has two curved lines.
A triangle can have no parallel lines.
A pentagon has no parallel lines.
it has too parallel lines!
A cone does not have any parallel lines
