Which of the following is the final step in bisecting a line segment? Keeping the compass at the same width, place the compass on the other endpoint and swing arcs on either side so that they intersect the first two arcs created. Mark the intersection points of the arcs, and draw a line through those two points. Place the compass on one of the endpoints, and open the compass to a distance more than halfway across the segment. Swing an arc on either side of the segment.

katherine:

is it b or D? @Vocaloid

theghost22:

Well, by following the steps of this problem you should find that the last step is not A or C

theghost22:

Step 1: Place the compasses on one end of the line segment.

theghost22:

Step 2: Set the compasses' width to an approximately two thirds the line length. The actual width does not matter.

theghost22:

Step 3: Without changing the compasses' width, draw an arc above and below the line.

theghost22:

Step 4: Then you have to again without changing the compasses' width, place the compasses' point on the other end of the line. Draw an arc above and below the line so that the arcs cross the first two.

theghost22:

Then the last step is: When you are using a straightedge, draw a line between the points where the arcs intersect.

theghost22:

Does this make sense?

katherine:

So, it's D?

theghost22:

Yes sir/ma'am

katherine:

I'm a ma'am....

And thank you
