Answer: Yes ΔRWS≈ΔQWT.
Explanation:
We know that when two chords intersect each other inside a circle, the products of their segments are equal.
Therefore,

Now in triangle QWT and triangle RWS
∠QWT=∠RWS [Vertically opposite angles]

Therefore, By SAS similarity rule
ΔRWS≈ΔQWT
Therefore, yes ΔRWS≈ΔQWT.
