pentagon
parallelogram or a rhombus * * * * * Incorrect. A parallelogram or rhombus have two pairs (ie 4) of parallel sides, and that is not the same as exactly two parallel sides. The correct answer is any polygon with with four or more sides of which only two are parallel. The only one of these with a specific name is a quadrilateral and the name is a trapezium.
It could be any irregular polygon other than a triangle.
There is not a name for such a polygon. A polygon with one million sides is called a megagon though..
A polygon is made of sides.
pentagon
Yes, it has sides that are straight line segments. Exactly one pair of opposite sides is parallel. Polygons do not have curved sides.

A polygon in the form of a trapezoid would fit the given description providing that it is not an isosceles trapezoid.
There is no polygon with one side.
It could be any irregular polygon other than a triangle.

A polygon is made of sides.
Just like a triangle is a polygon with 3 sides, A Quadrilateral(quad) is a polygon with 4 sides. Pentagon is a polygon with 5 sides and hexagon is one with 6 sides.
megagon (hecatomyriagon)
A polygon is a plane figure bounded by straight sides. An equilateral polygon is one in which all the sides are of the same length.
The perimeter of a polygon is the sum of the length of each of its sides. If the polygon is a regular polygon the you can calculate the perimeter as [number of sides] *[the length of one side]
