Yes.
An infinite number. A polygon with any number of sides can be equilateral (ie have sides of equal length).
Adding the lengths of the straight sides of any polygon will give its perimeter. In the case of regular polygons it will be the length of the side multiplied by the number of sides. But in the case of a non-regular polygon all the individual sides' lengths will be added to give you the perimeter.
Any polygon with 4 sides is a quadrilateral
Any regular polygon
The perimeter is the sum of the lengths of all sides.
A pentagon, which is a 5-sided figure, will have a perimeter equal to the sum of the lengths of all the sides. This will be true for any polygon; the perimeter of any polygon is the sum of the lengths of all the sides. If the pentagon is a regular pentagon, then the perimeter will be 5 times the length of one of the sides. For any regular polygon, the perimeter will be the length of one side times the number of sides in that polygon.
Any "regular" polygon.
To find the perimeter of any polygon, add up the lengths of all the sides.

A polygon in which all sides are congruent?Improved Answer:-Any regular polygon as for example an equilateral triangle or a square
A regular polygon has a center, much as a circle does. There are also the sides which are all the same lengths. Then there is the apothem which is any segment that goes from the center and is perpendicular to one of the polygon's side. Then angles are also parts and they are all the same. You might consider the perimeter a part and of course it is the sum of the sides.
Any Polygon can be a regular figure, if the figure has all straight sides and edges, with all the same length. If the decagon had all straight edges, sides, and same lengths of sides, it would be a regular figure. Otherwise, it would not, and would be an irregular Decagon. * * * * * That is not a correct answer. Any polygon, by definition MUST have all straight sides (which are the same as edges). What makes a polygon regular is that all the sides are the same length AND that all the interior angles are the same measure. Both these conditions must be met.
