Answer: If there are 12 identically matched points on the picture of the sun, then the angle between any two adjacent points is 360/12 = 30 degrees.
When you line up two suns directly on top of each other, all of the matched points on the top sun will line up with the corresponding matched points on the bottom sun.
To find the least number of degrees that you can rotate the top sun so that the two suns are perfectly aligned again, you need to find the smallest angle that is a multiple of 30 degrees.
The smallest angle that is a multiple of 30 degrees is 360 degrees, which is equivalent to rotating the top sun all the way around once. Therefore, the least number of degrees that you can rotate the top sun so that the two suns are perfectly aligned again is 360 degrees.
