If the cylinder is standing on its flat face, the horizontal cross section is a circle. Otherwise, it is a line or a rectangle.
hello
If you're talkin about sumthin like a soup can then its a cylinder
It is a cylinder since it has three bases of measurement rather than the two that a circle has.
A rainbow is an example of an arc shape, as is any object or drawing that has a curve conforming to a section of the the circumference of a circle.
A square or rectangle has all right angles. More complex shapes can also have all right angles, notably forms such as the outline "cross" (e.g. Red Cross), which is an irregular dodecagon having twelve sides. The Greek cross is equilateral, the Latin cross is not.
The definition of a line of symmetry is a line that can be draw down the center of any shape or object to show mirror image of the other side. where each side is a mirror image of the other side. Now for a horizontal one, it just means that if you cut the figure in half, horizontally it will make a mirror image.
It is sometimes referred to as the shape's "plan".
The cross section of cylinder along its length (parallel to the axis of symmetry has the shape of a rectangle.
You cannot have a 2d cylinder. The 2d cross section will depend on the plane of the cross section.

A cylinder is a three dimensional shape with a uniform circular cross section and a finite length.
