360 Divided By How Many Sides The Shape Turned.
triangles have 0 rotational symmetry
it has 5 rotational symmetry
It has 1 order of rotational symmetry.
If it's a regular 8 sided octagon then it rotational symmetry to the order of 8
A line has 180 degrees rotational symmetry.
A pentagon has roatotional symmetry only if it is a regulat pentagaon. In that case, it has a rotational symmetry of 360/5 degrees and its multiples. That is, 72, 144, 216, and 288 degrees.
it has order two (180 degrees)

A line has rotational symmetry of order 2.
Rotational symmetry of order 1.
It has 1 order of rotational symmetry.
Rotational symmetry is when you turn or rotate a shape and it still looks the same. A circle is the most common answer. However, it you rotate a square about 90 degrees, it still looks the same, so it is considered rotational symmetry. Technically, any shape can have rotational symmetry because it you rotate it 360 degrees, it still looks the same.Definition of rotational symmetry:Generally speaking, an object with rotational symmetry is an object that looks the same after a certain amount of rotation. An object may have more than one rotational symmetry; for instance, if reflections or turning it over are not counted. The degree of rotational symmetry is how many degrees the shape has to be turned to look the same on a different side or vertex. It can not be the same side or vertex.
A general parallelogram has rotational symmetry of order two.
