"The angle at the centre is twice the angle at the circumference". Ever heard of this theorem before?

zarkam21 (zarkam21):

Yes I think so

OpenStudy (benthicflare):

Yes so you are given the angle at the centre of the circle. What is the angle at the circumference then?

zarkam21 (zarkam21):

50

zarkam21 (zarkam21):

So is the answer 50

zarkam21 (zarkam21):

well you said twice so 100?

OpenStudy (benthicflare):

The angle at the CENTRE is twice the angle at the CIRCUMFERENCE. Would you like to try again?

zarkam21 (zarkam21):
