Final answer:
The construction of a parallel line to DF through point F, uses a straightedge and compass construction. To construct a bisector of angle EDF that goes through the parallel line, follow the steps.
Step-by-step explanation:
To construct a parallel line to DF through point F, we can use a straightedge and compass construction. Here are the steps:
- Draw a line segment DF.
- Place the compass at point F and draw an arc that intersects line DF at two points.
- Without changing the compass width, place the compass at one of the points where the arc intersects line DF and draw another arc.
- Draw a line through point F and one of the points where the second arc intersects line DF. This line is parallel to line DF.
To construct a bisector of angle EDF that goes through the parallel line we just created, follow these steps:
- Place the compass at point D and draw an arc that intersects the lines DE and DF.
- Without changing the compass width, place the compass at point E and draw another arc that intersects the first arc at two points.
- Draw a line through point E and one of the points where the arcs intersect. This line is the angle bisector of angle EDF that goes through the parallel line.
