Where can I find the whole worksheet, looks perfect.

Thanks. I cannot get no 24! Hint?

if you reflect the triangles onto the underside of the diameter line (or, essentially, extend all the lines), you get a bunch of similar triangles and can deduce from that.

I cannot solve the question 24..please can u make the solution available

Answers are on the sheet. Reflect the shapes across the diameter to help

Is there some significance with the dot on the diameter between both angles a ? Otherwise extending the lines and reflecting in the diameter are surely different outcomes? Please help 😀

I’ve managed to work out θ = 50° by reflecting the triangles along the diameter then making a cyclic quadrilateral to figure out the angle to the left of theta, then making another cyclic quadrilateral to find theta. But I’m still unsure of the relevance of angle a. Is it necessary to find it?

Thanks

How do you actually solve no. 24 step by step as extending the lines and reflecting across the diameter are 2 different things?
