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. $|5-(-2)|=|5+2|=|7|=7$
