The diagram shows a cyclic quadrilateral PQRS with its diagonals intersecting at K. Which of the following triangles is similar to triangle QKR?
\(\bigtriangleup\) PQK
\(\bigtriangleup\) PKS
\(\bigtriangleup\) SKR
\(\bigtriangleup\) PSR
Explication
It is angle PKS, angles in the same segment. Therefore, PKS is congruent with QKR
