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.
No, a regular isosceles triangle will not tessellate. In order for a shape to tessellate, it must be able to fit together with copies of itself without any gaps or overlaps. Regular isosceles triangles have angles of 90, 45, and 45 degrees, which do not allow for a repeating pattern that covers a plane without any spaces. Regular polygons that tessellate include equilateral triangles, squares, and hexagons.
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!
A regular polygon will tessellate if its interior angle divides 360 evenly.
The only regular polygons are those with 3, 4 or 6 sides.

A regular pentagon
A regular pentagon is one example.
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.
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.
