Thanks :D
btw have you got any detailed notes on this topic?
Although i know all the properties but still i'm not able to solve Qs of this topic :( (?_?)
the questions are a bit tricky but before solving the past papers u need to solve questions that need u to apply only some of the rules rather than the whole set
after that u can move on to past papers
the trick is to visualize the diagram in every possible way and apply each of the rules to it
for example, if in the diagram there is a tangent to a circle and a line passing from the centre of the circle is touching the tangent, u can easily apply the rule
''the angle between the tangent touching the circle and the line passing from the centre of the circle is 90 degrees'

AOB = 128.
And if an angle from chord AB was subtended at the circumference, it would be half of 128 that is 64.
That will form a cyclic quadrilateral, and AQB = 180 - 64 = 116.

Then, 116 + 5a + 3a = 180
8a = 64
a = 8.

Then, you will look at triangle AQP.
116 + 3(8) + b = 180
140 + b = 180
b = 40

thnx dude

but b is wrong, there is angle bqp as well that shud be added to 116 but u haven't added it
