For the line segment RS below, the green thing is the locus.
It is true to scale on a standard screen, 0.75 from each
point on line RS. 

   {{{drawing(450,1350/7,-7,7,-3,3, 
locate(-4,0,R), locate(4,0,S),
line(-4,0,4,0), green(line(-4,2,4,2), line(-4,-2,4,-2),

arc(-4,0,4,-4,90,270), arc(4,0,4,-4,270,450)) )}}}
