What is the next step in this construction? a. measure the distance from point r to point e using a compass. b. use a straightedge to connect point r with the arc below the line. c. place the compass on point rand draw a small arc above the line. d. place the compass on point e and draw a small arc below the line and beneath point r.

D. Place the compass on point E and draw a small arc below the line and beneath point R.

Step-by-step explanation:

According, to given construction we need to draw the a perpendicular on a line m from a point R above the line.

According to given figure, we have given a line m and R is a point above the line then they placed the compass on point R and draw the an arc by cutting line m at the points E and F. In next step we need to  

D. Place the compass on point E and draw a small arc below the line and beneath point R.
