Question

I need geometry help. I'm not looking for someone to just give me the answer, I just want to understand it and know how to do it. Diagram and questions posted below. There's two of them.

Answer 1

what is the measure of angle BFC

Answer 2

90 degrees

Answer 3

So because the central angle BFC is 90 degrees, this means the measure of arc BC is also 90 degrees

this is because central angle BFC cuts off minor arc BC

Answer 4

similarly, central angle CFD = 45 degrees

so minor arc CD = 45 degrees

Answer 5

thank you so much!

Answer 6

so do you see how to do the rest?

Answer 7

yes i do, thanks again.

Answer 8

you're welcome
