yes it does. a polygon has to be a closed figure with a least three sides and it can only have straight sides--no curves
Polygon
An equilateral triangle has three equal sides1. 1. Any triangle has only three sides. A triangle is a closed figure that is bounded by three straight lines.
A polygon is a 2-dimensional shape with 3 or more sidesa closed plane figure with three or more sides that are straight
A polygon is a closed figure bounded by sides. A triangle is a closed figure bounded by three sides. Therefore, according to the definition of polygon triangle is a polygon.

Three straight sides Closed figure two dimensional three angles
Polygon
a figure, esp. a closed plane figure, having three or more, usually straight, sides.
A polygon is any closed plane figure bounded by three or more straight sides.
A polygon. It has to have straight sides, so that it can be divided into triangles.
A closed 2-dimensional figure bounded by straight lines. A polygon can have three or more sides.
It is a 2-dimensional figure. It has THREE or MORE sides.
square
no, a polygon is a closed plane figure bounded by straight sides. so, it can have more than three sides.an example would be a rectangle, square, pentagon....
A three sided closed plane figure (shape) is a triangle.
