Answer:
B
Step-by-step explanation:
Angle ABD is congruent to angle CBD--->Definition of perpendicular lines
Segment DB is congruent to Segment Db--->Reflextive property of congruence
Angle ADB is congruent to angle CDB--->angle bisector theorem
2 angles and 1 side is congruent, therefore <em><u>the triangles are congruent by the ASA Congruence Theorem</u></em>
