PT is a tangent to the circle PRQ, and QR is a secant intersecting the circle in Q and the line QR intersects PT at T. Prove that triangle PRT is similar to triangle QPT

I can't remember the precise theorem but there is one that you can use to state <PQT = <RPT. Using the fact a tangent to radius is 90 degrees we can state that <QPT = 90 degrees. From there it is quite easy to prove similarity.

would it be alternate segment theorem?
