An impossible figure in two dimensional space. A Dacagon has ten sides and must have ten angles.

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°
If you meant decagon, A polygon with ten angles and ten sides.
The name of a regular polygon, with ten equal sides and ten equal angles, is a decagon, from the Greek word "deka", meaning ten.

The interior angles of a 10 sided polygon add up to 1440 degrees
A shape with ten sides and seven vertex is impossible. There must always be the same amount of sides as vertex in a shape.
A polygon that has 10 sides that are not all equal* * * * *Got the right idea but wrong in the detail. It is a polygon with ten sides in whicheither at least two sides are unequal, orto angles are unequal.Thus a polygon with ten equal sides, and 9 equal angles but the tenth angle being different, would be irregular.
The sum of the measures of the exterior angles of any polygon, regular or irregular, is always 360 degrees. In a regular polygon with ten sides, each exterior angle measures 360 degrees divided by the number of sides, which in this case is 36 degrees. Therefore, the sum of the measures of the exterior angles of a regular decagon is 10 multiplied by 36 degrees, which equals 360 degrees.
