Circle geometry theorems

(1/1)

fkkiwi:
Hey

Is it necessary to write out the circle geometry theorem is full when proving something? (e.g. 'the angle between a tangent and a chord through the point of contact is equal to the angle in the alternate segment' takes a long time to write)

RuiAce:
That particular one can be shortened to the "alternate segment theorem". But for everything else, yes.
