Question

δjik ≅
δtrs
δrst
δstr
δtsr

Explanation:

Step1: Identify corresponding angles and sides

In congruent triangles, corresponding angles and sides are equal. In \(\triangle JIK\) and the other triangle, we match the angles and sides based on the markings (equal - angle marks and equal - side marks).

Step2: Match the vertices

The angle at \(J\) (in \(\triangle JIK\)) corresponds to the angle at \(S\), the angle at \(I\) corresponds to the angle at \(T\), and the angle at \(K\) corresponds to the angle at \(R\).

Answer:

\(\triangle TSR\)
