A regular pentagon
No Internat angle of a regular octagon is 135°. No multiple of 135° will make 360°. Thus at any point there can be at most two octagons and a 90° gap. Ratty
The desk itself is not a polygon since it is a three-dimensional object, but a polygon is a two-dimensional object. Perhaps you are asking whether the top of the desk is shaped like a regular polygon. Most school desks have rounded corners (to reduce injuries) and thus would not be regular polygons. Some also have ridges and other irregularities for pencils and the like. And most are probably a little wider than they are long. But I'm sure there are some school desks somewhere whose tops are shaped like regular polygons. You'll have to examine the desks that your school uses and compare them to the definition of a regular polygon in your math book.
area of a polygon is the amount of area inside the polygon. A square is a polygon and its area is the side length squared, ie times itself. Some polygons are harder to find the area of.
60 degrees. You find this by taking 360 and dividing by the total sides (6) which leaves you with the degrees of the exterior angles, this exterior angle is how little you can rotate any polygon for that matter.
No, it is not possible.
It can be used only if the measure of its interior angle is a factor of 360 degrees.
It is extremely difficult to explain how since it is, in fact, impossible!
The only regular polygons are those with 3, 4 or 6 sides.
A regular polygon will tessellate if its interior angle divides 360 evenly.

A regular pentagon
Tessellation is defined as the tiling of a plane using one or more geometric shapes, called tiles, with no overlaps and no gaps. In mathematics, tessellations can be generalized to higher dimensions. A periodic tiling has a repeat pattern. A regular quadrilateral can be used by itself to make a tessellation.
A regular pentagon is one example.
In order to make a tessellation, many versions of the shape need to be able to be slotted together without any space between them. This means that, at the points where the corners meet, the angles should add up to 360. In the case of squares, the angles are 90, and four of these make 360, so squares can tessellate. If a polygon has an angle measure of 140 degrees, then no amount of these angles can add up to 360, as 140 isn't a factor of 360. Thus the shape would be unable to tessellate in the strict mathematical sense.
