The Pentagon is a famous building that has an unusual shape, that of a pentagon or 5-sided polygon. But most buildings are shaped like polygons. It is just that they are shaped like rectangles and squares, which are also polygons.
A 6 sided hexagon can be a regular or an irregular shaped polygon
Pyramids are known with triangular and square bases. In theory, you could build a pyramid using any regular polygon as a base.
A seven sided polygon
12Infinitely many all different:As it is only the area that matters, the perimeter can be any shape:An equilateral triangle (with sides approx 3.398 units)A square (with sides approx 2.236 units)A regular pentagon (with sides approx 1.705 units)A regular hexagon (with sides approx 1.387 units)A regular heptagonA regular octagonA regular nonagonA regular decagonA regular hendecagon (11 sided polygon)A regular dodecagon (12 sided polygon)A regular triskaidecagon (13 sided polygon)A regular 14 sided polygonA regular 15 sided polygonA regular 16 sided polygon...A circle (with radius approx 1.262 units)And there are also the non-regular shapes, eg an L shaped hexagon, a kite, a parallelogram which can have an area of 5 square units.

A 6 sided hexagon can be a regular or an irregular shaped polygon
A regular polygon means a shape that has all equal lengths and angles. A couple examples are a square, an equilateral triangle, and a octagon shaped like a stop sign.
No, because a hexagon is not shaped like a stop sign. The latter have 8 sides.
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.
Yes. A polygon can have any number of sides over 2. There are regular polygons with any number of sides more than 2 as well. For example, stop signs are shaped as a regular octagon, a regular 8-sided polygon.
No. A regular polygon has all sides the same length and all angles the same size. A regular pentagon has 5 angles each 108 degrees. A house-shaped pentagon does not have all angles the same size, so therefore it cannot be regular.
I think u wanted to say 5 sided polygon & not 5 shaped polygon And a 5 sided polygon is a pentagon (penta meaning 5). hexagon is a 6 sided polygon
A dodecagon is a 12 sided polygon which can be regular or irregular and its interior angles add up to 1800 degrees
