Step-by-step explanation:
Figure A is not congruent
Figure B is triangle ABC
Triangle ACD is congruent to triangle CDB
line AC = line CD
Postulate: SAS (Side, Angle, and Side)
Figure C is contains two right angled triangle
Triangle DAM is congruent to triangle CBM
Line DM = Line CM
Postulate: SAS (side, Angle, and Side)
Figure D contain two similar right angle triangle and also they are congruent
Postulate : SAS (Side, Angle, and Side)
