- 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 at the centre of the circle is twice the angle at the circumference subtended by the same arc.
- 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
- Angles in a triangle add up to a sum of 180 DEG.
