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.
