Question

Need help .... Regular octagon ABCDEFGH rotates 360 degree clockwise about it's center . After how many 45 increments will A' ( the image of the A coincide with F

Answer 1

I'm assuming that as you go from A to B to C etc you are going in a clockwise fashion.

Going from A to B means you've rotated 45 degrees. Then from B to C, you've gone 45 more degrees. So how many times do you have to do this to land on F?

Answer 2
