A triangle (not traingle) is a polygon. It can be a regular polygon but need not be.
It is an equilateral polygon. It is not a regular polygon. For the polygon to be regular, it is not enough for the sides to be congruent: all the angles need to be congruent as well.
No. A polygon can be symmetric but need not be. In fact, the majority of polygons are not symmetrical.
A polygon is a closed plane figure consisting of straight lines. So a square is a polygon, a pentagon is a polygon. Just draw any closed figure with straight lines and you have a polygon.
The parallel sides of a polygon are sides that are segments of parallel lines. A polygon need not have any parallel lines. A triangle, for example, is a polygon that cannot have parallel lines.

When I was taking a test in math, I had to describe a polygon.
the polygon would be a square
It can be but need not be.
It can but need not.

No, a cylinder is not a polygon. It is not a polygon because it has curved sides. In order to be considered a polygon, it would need to have flat sides. Also, a polygon is a 2 dimensional shape but a cylinder is a three dimensional shape.
