Answer:
D.252
Step-by-step explanation:
In this question, We have to find which rotation about its center will carry a regular decagon onto itself?
A decagon : 10 sided polygon
As we know, a full rotation can be 360°.
For a decagon: 360/10 =36
For a decagon, any multiple of 36 can map onto itself.
In our options only 252 is the multiple of 36.
So, correct answer is option D 252
