Answer
a) No
b) Yes
Work Step by Step
a) The absolute value of a number is the positive version of that number. (If the number is already positive, the absolute value of the number is just itself.)
AB=$|-2-3|=|-5|=5$
DE = $|10-14|=|-4|=4$
The distances are not the same, so the segments are not congruent.
b) The result is the same because the distance a number is from 0 is the absolute value.
$|5-(-2)|=|5+2|=|7|=7$
