a triangle
No. To be a polygon a figure must be "closed", that is, enclose an area. At least three line segments are required to enclose an area.
Every closed figure with at least 4 sides has at least 2 diagonals. Every quadrilateral (figure with exactly 4 sides) has exactly 2 diagonals. That includes all parallelograms, rhombera, rectangles, squares, trapezoids, diamonds, and kites, as well as all other irregular quadrilaterals.

A three sided closed plane figure (shape) is a triangle.
depends on whether or not they form a closed figure. a polygon is a closed figure consisting of at least three sides

Polygon
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
Pentagons are a type of polygon. A polygon is a flat, closed, geometric shape that has at least three sides.
A polygon is a 2-dimensional closed figure that has at least three sides. A pentagon is a 2-dimensional closed figure that has five and only five sides, so it is a kind of polygon.
A polygon is a closed figure with only straight edges. A polygon has at least 3 sides.
