, and A". Join these points to P by lines cutting 0" D" in C, B', and A'. Next draw a line P D (Fig. 44) equal to P D (Fig. 43), and with P as centre and P C, P B, and P A" (Fig. 43) successively as radii describe arcs c c, hh, and a a. With D as centre and radius equal D c (Fig. 43) describe arcs… … successively as centres and same radius describe arcs cutting arc a a in A and A right and left of PD. Join the points C, B, and A right and left of P D to P. With P as centre and P D" (Fig. 43) as radius describe an arc cutting P D in D". With same centre, and P C (Fig, 43) as radius, describe arc…
