Answer:

C. AB=CD not necessarily true

Step-by-step explanation:

AD = DB True because the width of the compass was the same and hence the radius was same for both centers A and B

B. AE=EB True

CD makes the perpendicular bisectors if arcs are made with compass of same width

C. AB=CD . There is no property which says that it is necessarily true

D. AC=CB True because the width of the compass was the same and hence the radius was same for both centers A and B

38, 88, 90, 91, 93, 95, 100

the median would be 91, which looks better.

the mean would be 85.
