Hello! Im glad i found this forums, i need some help. I am stumped on this and have been trying everything, but i seem to be missing something.

Here is the Question:

In the picture given PQ is the centreline of circle PWRQ.SP is a touchline of the circle.QWT is a straight line with T on PS

1. i have to prove that corner P1 = corner P2

2. I have to prove that SRWT is a koordevierhoek(i dont know what its called in english, but when you have 4 lines in a sircle and they all touch the sides)

Sorry for not using correct terms but im afrikaans normally.

Now i have seen that corner w = corner p1 (same circle segment on same basis)

And that R 2 = 90 degrees

but from there i am stuck, can someone point me into the right direction and help please?
