Question

The formal definition of a polygon states that a polygon is a closed plane figure formed by _____ or more segments called sides. Each side intersects exactly two other noncollinear sides, one at each endpoint.
A. four
B. one
C. zero
D. two
E. three

Answer 1

The answer would be three. The reasons are clear. You can't form a closed figure when you just have two sides. All they would do is just intersect each other. Also, one side must intersect with two other noncollinear sides. This means that a polygon has to have at least three sides.
