Transformations of Graphs |
Outside of bracket: y changes only. Inside of bracket: x changes only (the operation sign changes). Number x f(x): graph will be thinner. F(number x x): graph will be wider. |

|
Parallel Lines |
Alternate angles: Z shape Allied angles: Add to 180° Corresponding angles: F shape |

Circle Theorems |
1) A tangent and radius meet at 90°. 2) Two radii form an isosceles triangle. 3) The perpendicular bisector of a chord passes through the centre of the circle. 4) The angle at the centre of a circle is twice the angle at the circumference. 5) The angle at the edge of circle (from a diameter line) = 90°. 6) Angles in the same segment are equal. 7) Opposite angles in a cyclic quadrilateral add up to 180°. 8) Tangents from the same point are the same length. 9) The angle between a tangent and a chord is always equal. |
