No. A circle is not a polygon.
polygons
All three dimensional figures have more faces than a one dimensional figure. There are an infinite number of one dimensional points on a three dimensional figure
A sphere, a cylinder and a cone all have properties of a circle in them
A triangular pyramid is a pyramid with a triangular base; all pyramids are by definition three-dimensional figures, so a triangular pyramid is indeed 3D.
The three dimensional figures are called Space figures
There are infinitely many types of 3 dimensional figures. It is impossible to name them all.
All six-sided two dimensional figures are hexagons.
There are none to be seen but if you meant 4 sided figures then they are quadrilaterals
No. A circle is not a polygon.
All polygons are 2-dimensional figures bounded by straight lines. Since they are 2-d they are included in the set of all 2-d figures. But since they can only have straight sides, they cannot account for all 2-d figures.
Rectilinear figures are figures that are produced using just line segments. All of the polygons are rectilinear figures and many 3-dimensional solid shapes are as well.

No; it simply means they are all on the same plane, as are two-dimensional figures.
All three dimensional figures have more faces than a one dimensional figure. There are an infinite number of one dimensional points on a three dimensional figure
TRUE for 2-dimensional figure. False for 3-dimensional figures.
A triangle (and all 2-dimensional or plane figures) have only one face.
