A decagon has 10 sides, so it also has 10 angles. Each angle of a decagon is 36 degrees (360 degrees divided by 10). Therefore, a decagon has 10 angles of rotation symmetry.
It depends on whether or not the decagon is a perfect decagon or a complex decagon. However, a perfect decagon has no acute angles.
A decagon has ten vertices.
A regular decagon has rotational symmetry = 10.For irregular decagons, it could be less (either 2 or none.)
A diamond has two rotation symmetry. It is possible to have a diamond that does have four of rotation symmetry.
A decagon will always have its interior angles measure 1480
A regular decagon has 10 lines of symmetry. Each line of symmetry can be drawn through a vertex and the midpoint of the opposite side, as well as through the midpoints of two opposite sides. This symmetry reflects the decagon's equal angles and sides, allowing for multiple symmetrical divisions.
A decagon need not have any lines of symmetry. It can also have 1 or 10 lines of symmetry.
A decagon need not have any lines of symmetry. It can have 10.
It depends on whether or not the decagon is a perfect decagon or a complex decagon. However, a perfect decagon has no acute angles.
