Answer: Reflexive property of congruence
Explanation:
In geometry , the reflexive property of congruence says that each every geometric is congruent to itself.
For example : A triangle is congruent to itself, a angle is congruent to itself and so on....
Given statement : segment AB is congruent to segment AB.
Since line segment is a geometric figure.
Thus, this statement shows the reflexive property of congruence.
