They have the same angle relative to any plane or line and never intersect.
Two pairs of parallel lines.

In Euclidean geometry, parallel lines are the same distance apart and never meet.
Two sets of parallel lines meeting at right angles.
Yes, it is possible for a shape to have at least one pair of parallel lines and no lines of symmetry. For example, an irregular trapezoid has one pair of parallel sides but lacks any lines of symmetry due to its uneven angles and side lengths. This demonstrates that parallel lines and symmetry are independent properties in geometric shapes.
Its diagonals are congruent. One set of parallel sides. The other two non parallel lines are congruent.
An irregular quadrilateral can have zero, one, or two pairs of parallel lines, but typically it has no parallel lines. By definition, an irregular quadrilateral does not have equal sides or angles, which means it does not conform to the properties of specific types of quadrilaterals like rectangles or parallelograms that have parallel sides. Thus, the most common scenario for an irregular quadrilateral is having no parallel lines at all.
A parallelogram consists of two pairs of parallel lines. Everything else follows from this.
1. Two sets of parallel lines 2. All angles are 90 degrees3. Four lines of symmetry
An ellipse does not have parallel lines in the traditional sense, as it is a smooth, closed curve defined by its geometric properties. However, one can draw tangents to the ellipse at various points, and some of these tangents can be parallel to each other. In a broader mathematical context, while the ellipse itself does not possess parallel lines, the concept of parallelism can apply to lines related to the ellipse, such as its axes or tangents.
