Which Postulate/Theorem below would prove that the triangles shown below are congruent?
a. SSS
b. SAS
c. AAS
d. ASA

Answer:
Correct answer is D. ASA
Step-by-step explanation:
Let us first define ASA congruence rule:
2 triangles are called congruent according to ASA congruence rule if 2 angles of the triangle and the corresponding side between these two angles are equal to each other.
In the question figure, we can figure out following conclusions from Triangles [tex]\triangle SRT\text{ and }\triangle WXY[/tex] respectively:
As per the definition of option d) ASA congruence, the triangles are congruent.
