Yes if it is a regular polygon
It is a regular 10 sided decagon
''Decagon'' is any polygon with ten sides and ten angles ''Regular decagon'' is a polygon with ten sides of equal length and all angles equal to 144°
It is: 360/36 = 10 sided regular decagon polygon
Any polygon is regular if its sides are all the same length, or irregular if they're not. If all 10 sides of your decagon are the same length, then you have a regular decagon. If they're not, then you have an irregular one.
A ten-sided polygon is called a decagon. A decagon has ten internal angles of 144-degrees. All sides of a regular decagon are equal length.
A regular decagon, or 10-sided polygon, has interior angles of 144
It is best described as a regular 10 sided polygon or as a regular decagon.
As a decagon has 10 sides, the measure of the exterior angle for a regular decagon is 360/10 = 36°
