No - a pentagon has 120 degree rotational symmetry.
If it is a regular 5 sided pentagon then its order of rotational symmetry is 5
Yes, a regular pentagon has rotational symmetry. It can be rotated around its center by multiples of (72^\circ) (360° divided by 5) and still look the same. This means it has five distinct positions in which it can be rotated without appearing different. Thus, the regular pentagon exhibits rotational symmetry of order 5.
A regular pentagon or a 5-pointed star have rotational symmetry of order 5.
a pentagon has 10 lines of symmetry
Yes, a regular pentagon has rotational symmetry.
They have not got any rotational symmetry
No - a pentagon has 120 degree rotational symmetry.
Yes
Yes.
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 both because it has 5 lines of symmetry and rotational symmetry to the order of 5
It need not have any rotational symmetry or it can have 5.
If it is a regular 5 sided pentagon then its order of rotational symmetry is 5
it is order 5
a pentagon has rotational symmetry if its a regular pentagon. if you add all 5 sides together you will get 360 degrees
This is a little bit like asking why a square has four sides. A regular pentagon is defined in such a way as to require that it has 5-fold rotational symmetry.
