Answer:

                (a) Two line segments are congruent if they have the same length. (b) Among two congruent angles, one has a measure of \[{{70}^{o}}\] the measure of the other angle is also \[{{70}^{o}}\]. (c) When we write \[\angle A=\angle B,\] we actually mean \[\angle A\cong \angle B,\]
