velikii [3]

Answer:

Correct answer is <em>D. ASA</em>

<em />

Step-by-step explanation:

Let us first define <em>ASA congruence</em> 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 <em>equal </em>to each other.

In the question figure, we can figure out following conclusions from Triangles \triangle SRT\text{ and }\triangle WXY respectively:

  1. \angle TRS = \angle YXW
  2. Side RS = Side WX
  3. \angle TSR = \angle YWX  

As per the definition of option d) ASA congruence, the triangles are congruent.
