Answer:
D. 360°
Step-by-step explanation:
We have been given an image. We are asked to find the least angle measure that will map the given figure onto itself.
We can see that our given polygon is an irregular polygon.
To map the given polygon onto itself, we have to rotate it a full round, that is 360 degrees, therefore, the least angle that maps the given polygon onto itself is 360 degrees and option D is the correct choice.
