If you need only one or two lines then use pst-eucl:


\documentclass{article}
\usepackage{pst-eucl}
\usepackage{auto-pst-pdf}

\begin{document}
	
\begin{pspicture}[showgrid=true](-4,-5)(4,0)
\psset{PointSymbol=none,PointName=none}
% Comment the above line to see all points
\pstGeonode(0,0){O}(0,-4){A1}(0,-5){A2}(-3,-1.5){B1}(-2.5,-3){B2}
\psarc(O){4}{225}{315}
\psarc(O){5}{225}{315}
\pstInterLC{B1}{B2}{O}{A1}{M1}{M2}
\psline[linecolor=red]{->}(B1)(M2)
\pstOrtSym{O}{M2}{M1}[M1']
\psline[linecolor=red]{->}(M2)(M1')
\pstOrtSym{O}{M1'}{M2}[M1'']
\pcline[linecolor=red,nodesepB=15mm]{->}(M1')(M1'')
\end{pspicture}	
	
\end{document}
