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.
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.
Slanting. A slash (/) is oblique

It is a shape that is not regular.
It is a line segment.
it is an oblique straight oval.
A diagonal line is a straight line that connects two non-adjacent corners of a shape, typically forming a 45-degree angle with the sides of the shape. An oblique line, on the other hand, is any line that is neither horizontal nor vertical, and can be at any angle other than 90 degrees. In essence, all diagonal lines are oblique, but not all oblique lines are diagonal.
If the angle from the base to the highest point is a right angle, it is right. If not, it is oblique.
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
