Multiple choice quick parallelogram question. Thanks :)

OpenStudy (anonymous):

Which statement can you use to conclude that quadrilateral XYZW is a parallelogram? A. line segment YZ is congruent to line segment ZW and line segment WZ is congruent to line segment XY B. line segment YZ is congruent to line segment XW and line segment WZ is congruent to line segment XY C. line segment ZN is congruent to line segment NW and line segment XN is congruent to line segment NY D. line segment YZ is congruent to line segment XW and line segment WZ is congruent to line segment ZY

I'm here. Now, you can tell that it's a parallelogram due to the nature of the center angles. What can you tell of them?

OpenStudy (anonymous):

I don't know how to do it

OpenStudy (anonymous):

@TheStarlingHasFlown i will give you a medal

OpenStudy (anonymous):

They are all right angles.

OpenStudy (anonymous):

so???

OpenStudy (anonymous):

A parallelogram is a square-like shape where the corners are connected into a single center point that are all right angles. I would show that the line segments are congruent. One moment while I confirm this.

OpenStudy (anonymous):

ok take ur time thanks... :)

OpenStudy (anonymous):

C is out of the question, can you see why?

OpenStudy (anonymous):

ya because zn is not congruent to nw

OpenStudy (anonymous):

Yes! Great! Now, what other answers can we rule out through this method? :D

OpenStudy (anonymous):

I think I get it, would it be B. ?

OpenStudy (anonymous):

I believe so. Try to get a second opinion, however. When in doubt, rule out.

OpenStudy (anonymous):

Yes!!!
