How to find the central angle of a sector if the values ​​of two angles of the lines, the circle relative to the x-axis are known?

Question

Mathematics

Basically the question is in the title. There are, say, 2 angle values, for example, 350 degrees and 10 degrees, you need to find out what angle the sector between them will have (the smaller sector), apparently it’s evening and I’m just stupid, but I can’t figure out how to calculate this universally

Answer 1

If these are not straight lines, but rays, and directions a,b lying from 0 to 360, then
min( abs(ab), 360-abs(ab) )
