Angle at centre is twice the angle at the circumference
Angle at centre is twice the angle at the circumference.
Adjust the point A to get the angle at the centre O = 60 and observe the angle at the circumference. [br]What is the angle at the circumference?
[math]60^\circ[/math]
[math]120^\circ[/math]
[math]30^\circ[/math]
What is the relationship between the angle at the circumference and angle at the centre O?
The angle at the circumference is TWICE at the angle at the centre O.
