Lesson Title: Circle Theorems Consolidation

Lesson Objectives:
 * Be able to recall and use all the theorems we have covered:
 * Angle at centre = 2x angle at circumference
 * Angles on same arc iin same segment are equal.
 * Angle in a semi-circle is 90 degrees.
 * Angle between the tangent and radius is 90 degrees.
 * Two tangents drawn from a point to a circle have equal length.
 * Opposite angles of a cyclic quadrilateral are supplementary.
 * Perpendicular from centre bisects a chord.

Homework:
 * Collect in their homework.

Starter:
 * Worksheet containing all the theorems they should know -- matching statement to picture, and inserting the missing words.
 * (Encourage them to stick this summary in their exercise books for revision.)

Starter Assessment:
 * Check everyone got this exercise 100% right.

Main Episode 1:
 * Work through GCSE Higher questions on Circle Theorems. (Questions taken from 2004 and 2005.)
 * Display the first two on the board -- encourage them to solve it with me.

ME1 Assessment:
 * Questions around the class.
 * Hand out next 3/4 as worksheets.
