If we're talking in purely geometric terms:
If the edges of a prism/cylinder make a right angle with the base, it is called a right prism/cylinder. If not, it is an oblique prism/cylinder...it will look as if it were slanting to one side instead of standing straight.
Similarly, if the top vertex of a pyramid/cone is directly above the center of the base, it is a right pyramid/cone. Otherwise, it is an oblique pyramid/cone. Again, it will look a bit askew.
It is a line segment.
If the angle from the base to the highest point is a right angle, it is right. If not, it is oblique.
Slanting. A slash (/) is oblique

Rectangular is an adjective, not a noun. So the answer depends on a rectangular WHAT! An oblique rectangular cone need have no line of symmetry.
It is a shape that is not regular.

it is an oblique straight oval.
If the angle from the base to the highest point is a right angle, it is right. If not, it is oblique.
There are two muscle pairs that help form the natural abdominal girdle The Internal Oblique and the Transversus Abdominis form the shape of the abdomen.
Oblique drawings are designed to show a three dimensional view of an object. It is a kind of a drawing that shows one face of the object in true shape, but the other faces on a distorted angle. Oblique is not really a '3D' system but a 2 dimensional view of an object with 'forced depth'.
internal oblique opposes the external oblique
