I divided the circle below using the following steps:
- made a perfect circle
- created two lines at 75 and 105° rotation
- used the pathfinder divide tool to separate the circle.
I want to know (how to calculate) the positions I would have to move each part of the circle to create an 80px gap. I would like to move each of them by an equal distance to create the 80px gap, as in the image. How can I find the new positions?
