pentagon a pentagon A pentagon is a Polygon with 5 sides.
Try tetradecagon. The name of the geometrical figure with 14 sides is being proposed to be Tetradecagon, Tetrakaidecagon.
This closed figure, with straight sides, is known as a Polygon.

Triangles by definition have three sides; a two-sided triangle is impossible. In fact, no closed geometrical figure can be created out of only two straight lines. An angle is not closed. A vesica piscis is not made of straight lines. (This is the lens-like shape created in the intersection of two circles.)

A polygon is a closed figure bounded by sides only. Triangle is the polygon of 3 sides and 3 vertices.
The name for a region of a closed figure is the Area.
Quadrilateral is the name fr a geometric figure with 4 sides.
If the figure has eight sides, but they are not equal, it has no special name. It would just be called an eight-sided polygon. A polygon is a closed figure made by joining line segments, where each line segment intersects exactly two others.
Shapes with no names are typically referred to as "irregular shapes." These shapes do not have specific labels such as circle, square, or triangle, as they do not conform to any standard geometric definition. Irregular shapes can have varying sides, angles, and measurements, making them unique and not easily categorized.
