These Are The Circle Theorems You Need To Know:
Opposite angles in a cyclic quadrilateral sum to 180° P, q and r are points on the circumference of a circle, centre, o. Angle at centre is twice angle at.
Rule 3, The Angle At The Centre Is Twice The Angle At The Circumference.
Use the diameter to form one side of a triangle. 1.!(a) in the diagram below, o is the centre of the circle and a, b and c are points ! Included are angles in the same segment and angle at the centre.
