Question

Regular octagon ABCDEFGH rotates 360° clockwise about its center. After how many 45° increments will A′ (the image of A) coincide with F?

Answer 1

3

Answer 2

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?

Hope this helps - Bree @Mkitchin it would be 3 if you were going counter clockwise, but this is asking for clockwise lol :)
