List all rotational symmetries for a REGULAR HEXAGON. Separate each measurement with a comma. You may use an " * " or "d" to represent degrees. IE: 360 degrees, should be entered as 300* or 300d. You may also use the function editor to insert a degree symbol " ° ".
A shape has Rotational Symmetry when it still looks the same after some rotation (of less than one full turn). How many times it matches as we go once around is called the Order. Think of propeller blades (like below), it makes it easier.
A regular hexagon has rotational symmetry. The angle of rotation is 60 degrees and the order of rotational symmetry is 6 as illustrated by the diagram below. However, a scalene triangle has no rotational symmetry because you cannot rotate it and get the same image:
I.e. if two triangles are rotated 90 degrees from each other but have 2 sides and the corresponding included angles formed by those sides of equal measure, then the 2 triangles are congruent (SAS). Further, regardless of how we re-position those triangles, they remain congruent.
25 de jul. de 2021 · The order of rotational symmetry (or degree of rotational symmetry) is the number of times an object looks the same when it is rotated a full turn of 360°. The shape must look as though it has not rotated at all. For example, a rectangle has rotational symmetry of order 2.
