can you help me solve this proof? pls only give me legitimate answers
thanks!

(I can't show the angle symbol thing so I'll just say the name)
We have : QPS = TPR
And we have to prove : QPR = TPS
QPR + RPS = QPS
TPS + RPS = TPR
Since QPS = TPR, QRP + RPS = TPS + RPS
Minus both side by RPS : QRP = TPS
