Answer:
Explanation:
Since segment AB is the perpendicular bisector of CD, it means that point M is the midpoint of segment CD and the two line segments MC and MD are congruent.
Therefore, we can conclude that statement (1) is always true: CB = DB, as both segments are congruent to MC and MD, respectively.
Statements (2), (3), and (4) are not necessarily true based on the information given.
