Circle Theorem 1
When an inscribed angle and a sector angle are subtended by the same chord, then the sector angle is twice the size of the inscribed angle
Circle Theorem 2
All inscribed angles subteneded by the same chord are equal (as long as they lie on the same side of the chord)
Circle Theorem 3
When a diameter subtends an inscribed angle, the measure of that angle is alwase 90
Circle Theorem 4
In a cyclic quadrilateral opposite angles are suplementery they add up to 180
Circle Theorem 5
A tangent line touches the circle at exactaly one point. a radius drawn to that point is perpendicular to the tangent
