For two plane mirrors inclined at angle θ, let n=360°/θ be an integer. Which statements are correct?

Select all that apply

• Option A

  If n is even, the number of images is n-1.

• Option B

  If n is odd and the object is on the angle bisector, the number of distinct images is n-1.

• Option C

  If n is odd and the object is not on the angle bisector, the number of images can be n.

• Option D

  For parallel mirrors, the number of images is finite.
