Circle Theorems Proof

WebCircle Theorem: The angle subtended by an arc at the centre is twice the angle at the circumference. This is one of the most useful circle theorems and forms a basis for many other angle facts within circles; In this theorem, the chords (radii) to the centre and the chords to the circumference are both drawn from (subtended by) the ends of the ...
