no solid figure has only face the only shapes that has 1 face is 2d shapes
A polygon is a closed figure bounded by sides only. Triangle is the polygon of 3 sides and 3 vertices.
A flat figure polygon is a 2-D figure. It can be a square rectangle decagon dodecagon nonagon heptagon hexagon triangle parallelogram rhombus trapezoid and I forgot what the 2-D name for an 11 sided figure. (2-D can only be shown on paper and a polygon is any CLOSED figure) Hope this Helps!!! A.S.
A sphere or an ellipse.
IF (and only if) the lines are al coplanar, then a polygon.

a closed, flat figure is a polygon. But it is only a polygon when it is not round.
The side that is curved, when placed by itself (without bending or manipulating in any way), is not a polygon, making the shape not entirely made of polygons. A 3D figure must be made by only polygons to be a polyhedron.
A polygon is made up only of line segments. If a 2-dimensional closed figure has even one curve line, then it is not a polygon.
There is no solid figure with only four edges. The smallest solid figure is the tetrahedron, made up of four triangular faces, but it has six edges.
It is a polygon, but only if it is all in one plane.

A polygon must be a closed figure with only straight lines.
No, the "U" shape is not a polygon. Polygons are closed figures made up only of line segments. The "U" shape includes a curved section, and is usually not a closed figure.
A polygon is a closed figure with only straight edges. A polygon has at least 3 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.
no solid figure has only face the only shapes that has 1 face is 2d shapes
