Circle Geometry general help and tips ! (1 Viewer)

[YashC3]

I got half yearly's coming up in about 2 weeks, and circle geometry is being tested. I absolutely suck at circle geometry. I know the proofs, but i can never get my head around harder questions?

Any advise or tips?

Cheers

aww i used to LOVE circle questions

well

1- practice makes perfect, do alot of questions. past hsc papers, past school papers, books (the purple book by jeff geha - step by step study guide or something is good if you're not good with the concepts of 3unit maths imo)

2- use 2 pro-numerals when labeling your angles. (a and b, x and y etc). using more than 2 will be too confusing imo.

3- and i think thats about it

its really hard to draw a nice circle, let alone a big one. i advise tracing the circle from the question sheet onto the answer paper.

Here's a tip, if you have an intuition feel about a question, go with it, even if that means drawing a line here or there.

oh! and during the reading time, after going quickly through the paper and making mental notes to myself, i'd attempt to do the circle question in my head first. i'd also use my finger nails to mark down angles and stuff, so when the exam actually start, i'd just write down my solution.

for ext1 i find its just a matter of knowing all the theorems by heart (else how would you know what moves you can take next)

circ geo questoins are like a game - to see whether you can move an angle from the start ot the end (i.e. proving what you need to prove)

you get better with experience - not really a crammable subject

Harder circle geometry questions involve "constructing" lines. These are the most annoying of questions.
