We went to circle center radius and we made a circle that the center was point P.
we went to line and we made a line from point A to B
we went to offset curve and we made two parallels lines from line R
we went to offset curve and we made a curve from curve C
we went to line S and we went to offset curve and we made two upper lines and two lower lines from line S and we did the same with line R. We connected the second upper left line from line S to second lower right line from line R and we connected upper right line from line S to lower right line from line R
