Question

Look at the figure. Which step should be taken next to construct a line parallel to AB ?
 
   Place the compass on point A. Open the compass to point P. Move the compass to point P and draw an arc that intersects AP . 
 Place the compass on point C. Open the compass to point D. Draw a small arc through point D. 
 Without changing the compass setting from the previous step, place the compass on point B. Draw an arc similar to the one already drawn. 
 Without changing the compass setting from the previous step, place the compass on point P. Draw an arc similar to the one already drawn.
