An Octogon
In a regular octagon, there can be multiple sets of parallel lines. Specifically, each pair of opposite sides of the octagon is parallel to each other. Since an octagon has 8 sides, there are 4 pairs of parallel lines, resulting in a total of 4 distinct sets of parallel lines.
There is no such shape. There is a heptagon (7-sides) or an octagon (8 sides) but not hectogen!

The slope of both lines is 8. So they're parallel.

An octagon had four pairs of parallel lines.
None.
An octagon need not have any parallel sides. But it can have any number from 2 to 8 lines that are parallel - in pairs, triplets or quartets.
If lines m and n are parallel, and 8 measures 110o, which is the measure of 7?
Yes. Parallel Lines are also two coplanar lines that do not intersect.
An octahedron is a closed 3-d shape with 8 polygonal faces. There are 257 topologically different convex octahedra. Some of these have no parallel sides whereas a right hexagonal prism has 3 quartet of parallel sides and one sextet.

The figure that has 4 pairs of parallel lines and 8 obtuse angles is a rectangular shape known as a rhombus. A rhombus is a quadrilateral with all sides of equal length and opposite angles of equal measure. In a rhombus, each pair of opposite sides are parallel to each other, resulting in 4 pairs of parallel lines. Additionally, since a rhombus has 4 angles greater than 90 degrees, it will have a total of 8 obtuse angles.
