A decagon need not have any but the default number (1) of rotational symmetry. It can have rotational symmetry of order 2, 5 or 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.
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 is a polygon with 10 sides and 10 angles. Each angle in a regular decagon measures 144 degrees. The sum of the interior angles of a decagon is 1440 degrees. Decagons have lines of symmetry that pass through the center of the shape and divide it into two equal halves.
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.
