Hey welshfella

OpenStudy (mathmale):

I agree with your choice. A bisector doesn't have to be perpendicular to the line it's bisecting.

OpenStudy (mathsucks321):

Thank you

OpenStudy (welshfella):

I beg to differ on that one The GIven statement says that the DE and JL are perpendicular

OpenStudy (mathstudent55):

It states "perpendicular bisector." BTW, your answer is incorrect.

OpenStudy (mathsucks321):

Oh

OpenStudy (mathstudent55):

If a line is the perpendicular bisector of a segment, then you can conclude two things. 1. The line and the segment are perpendicular. 2. The point of intersection of the line and the segment is the midpoint of the segment.

OpenStudy (mathmale):

mathstudent55 is correct; I'm wrong. I defer to mathstudent55 (who must be pretty sharp).

OpenStudy (mathstudent55):

Read the explanation above carefully. Pay attention to the second part.

OpenStudy (mathsucks321):

Um is it C They all look right

OpenStudy (mathstudent55):

The line bisects the segment. That means the line splits the segment into to congruent sections.

OpenStudy (mathstudent55):

Look at option A. According to what a bisector does, option A must be true. That was the first part of my explanation above of a perpendicular bisector. The bisector intersects the segment at the segment's midpoint. Option A must be true.

OpenStudy (mathstudent55):

Now let's look at option B.

OpenStudy (mathstudent55):

The line DE bisects the segment JL. The line DE splits the segment JL into two congruent sections, JK and KL. Do we know that the segment JL bisects the segment DE in the line? No. We are not told so.

OpenStudy (mathstudent55):

Can you conclude anything about the length of segments DK and KE?

OpenStudy (mathsucks321):

So is it B?

OpenStudy (mathmale):

mathstudent55: You're very thorough. Nice work!
