The postulate that proves that triangle AMD and KRM are congruent is AAS.
What are congruent triangles?
The triangles in which corresponding three things are equal are known as congruent triangles. They may be angle or a side.
How to identify postulate?
In triangle AMD and triangle KRM
Angle R =Angle M=50°
Angle M=Angle D=25°
KR=AM (Given in figure)
Because two angles are used and one side is used so the postulate is AAS (Angle Angle Side).
Hence the postulate which proves that triangle AMD and KRM are congruent is AAS which is option c.
