The Best Circle Theorems Worksheet References. Angle at the centre is twice the angle at the circumference. Give reasons for your answer.
Angle between radius and tangent = 90. The triangle aox is therefore isosceles and so ∠oxa = a. Angle at the centre is twice the angle at the circumference.
Oa = Ox Since Both Of These Are Equal To The Radius Of The Circle.
