  • Circle theorem
    • Angles in a triangle add up to a sum of 180 DEG.
      • Angle at the centre of the circle is twice the angle at the circumference subtended by the same arc.
        • And a triangle that joins the tangent and two other points on the circumference of the circle .
        • The angle between a chord and a tangent is equal to the angle in the alternate segment
    • Angle in a semi circle is a right angle.
    • Angles at the circumference in the same segment of a circle are even
    • Opposite angles sum to 180 in a cyclic quadrilateral
      • A radius bisects a chord at 90
