its in your hands i know you know its

Step-by-step explanation:

Place compass at point D, and draw an arc that intersects the arc above

DF ⇒ 1st answer.

Step-by-step explanation:

* Lets revise how to construct a perpendicular line to a line from point

 on the line

- Place your compass pin on P and draw an arc of any size below

 the line that crosses it at two points label them D and F

- Enlarge the distance of the compass and place the compass pin

 on point F and make a small arc above the line

- Without changing the distance of the compass, place the compass

 pin on point D and draw another arc intersects the arc from point F

- Use a straightedge to join the intersection point of the two small

 arcs with point P

* Now lets find the next steps in the drawing

∵ The face of the arc above DF is front to point F

∴ This arc is drawn from point F

∴ The next step is "Place compass at point D, and draw an arc that

   intersects the arc above DF"
