Is there a series of rigid transformations that could map triangle cap k cap l cap p to triangle cap q cap n cap m ? If so, which transformations?

A
No, triangle cap k cap l cap p and triangle cap q cap n cap m are not congruent.
B
No, triangle cap k cap l cap p and triangle cap q cap n cap m are congruent but triangle cap k cap l cap p cannot be mapped to triangle cap q cap n cap m using a series rigid transformations.
C
Yes, triangle cap k cap l cap p can be reflected across the line containing line segment cap k cap p and then translated so that cap p is mapped to cap m .
D
Yes, triangle cap k cap l cap p can be rotated about cap p and then translated so that caps l is mapped to cap n .

Which statement explains the best measure of variability to use to compare the data sets?

A
The range is the best measure because the distribution of zucchini weights is skewed left.
B
The median is the best measure because the data sets have different medians.
C
The standard deviation is the best measure because both data distributions are symmetric.
D
The mean is the best measure because the data sets have the same minimum weight.
