Circle Theorems
Angles formed by drawing lines from the ends of the diameter of a circle to its circumference form a right angle.
Angles in a cyclic quadrilateral ad up to 180 degrees
Tangents form a right angle at the radius
Area of sector = πr2 × A/360
Alternate segment theorem
Angles formed from two points on the circumference are equal to other angles, in the same arc, formed from those two points
Theangle a the centre is half the angle at the circumfrence
Arc length = 2πr × A/360
