Question

side - side - side congruence theorem
\\( \triangle rtv \cong \triangle vsr \\)

Explanation:

Step1: Recall congruence theorems

The Side - Side - Side (SSS) Congruence Theorem states that if three sides of one triangle are equal to three sides of another triangle, then the two triangles are congruent.

Step2: Analyze the given triangles

In \(\triangle RTV\) and \(\triangle VSR\), we need to check the side - side - side equality.
We know that \(TV = SR\) (by the given lengths in the first figure, assume the non - marked sides are equal as per the congruence setup), \(RV=VR\) (common side), and \(RT = VS\) (by the given lengths in the first figure).

Answer:
