Want this question answered?
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.
Assuming a circular cylinder:Cutting lengthwise, you get a rectangle.Cutting parallel to the circular bases, you get a circle. Cutting at an angle, you can get an ellipse - or a shape that has parts of an ellipse, as well as straight lines.
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 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.
it has too parallel lines!
A pentagon has no parallel lines.
A cone does not have any parallel lines
how many sets of parallel lines are in a triangle
A trapezoid has one set of parallel lines.
A cube has exactly 6 parallel lines.
2 pairs of parallel lines
