It is a six sided polygon. An example is a beehive.
A hexagon cannot have a sum. There can be the sum of its interior angles, its exterior angles, its side lengths, its area (and that of some other area), or other characteristics, but not of a hexagon.
it is a polygon with six sides A hexagon is a six sided shape. A hexagon is a six sided shape.
A regular hexagon and some irregular ones will tessellate, But in general they will not.
Has 6 sides, This figure is a polygon, Has six lines of symmetry.
No, a hexagon is not a tessellation. Some hexagons can tessellate a plane, others will not.
A plane shape with these characteristics is a "hexagon".
As far as I know, a hexagon has 6 angles whether it is regular or not. Some may be obtuse angles, but they still count. So a hexagon where some of the sides go 'in' rather than 'out' is still a hexagon.
A hexagon is a closed 2-dimensional shape bounded by six straight sides. It has six vertices and its interior angles sum to 4*pi radians (720 degrees).
You measure them. In some cases, you may know some other information about the hexagon, in that case you may be able to calculate them.
No, only some can.
1080 degrees
When referring to it as a hexagon is not a faux pas.
