Question

What is the centre of rotation of nonagon​

Answer 1

Answer:

A regular nonagon has 9 lines of symmetry and a rotational symmetry of order 9, meaning that it can be rotated in such a way that it will look the same as the original shape 9 times in 360°. Nine 40° of rotation about the center.

To find the measure of the central angle of a regular nonagon, make a circle in the middle (I'll let you do the picture)... A circle is 360 degrees around... Divide that by nine angles... So, the measure of the central angle of a regular nonagon is 40 degrees.

i hope you got the best answer..
