I do not understand exactly what you mean by corner P1?
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?
With the information you have given you cannot show this. You need to tellOriginally Posted by Emeraldswan
us more, possibly about R or the other angles. All we can say at present is
that angle PRQ (your R2) is a right angle.
koordevierhoek - cyclic quadrilateral?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)
I think you need more information. As described you can move P up and downSorry for not using correct terms but im afrikaans normally.

along the tangent, which allows the point R to move on the circle, which will
change the relative sizes of P1 and P2.

Thanks! i get it! And as for the second one, can you please check if this is correct then.
Angle W1 + Angle TWR = 180 (Angles on same straight line)
But P1 = W1 (Triangles on same basis and same circle segment)
That goes to say that W1 = S
Wich meens that S + TWR = 180
thus its a cyclic quadrilateral because opposite sides of cyclic quadrilateral makes 180
Thanks alot for all the help!!!
