      you need to know theorems 1 - 21

      If you are talking about proofs of theorems, here is the answer:

      JCO - no theorem proofs required

      JCH - 4, 6, 9, 14, 19

      LCO - no theorem proofs required

      LCH - 4, 6, 9, 11, 12, 13, 14, 19 (which is really the 5 JCH ones plus 11, 12, 13)

      Happy to help,

      I thought it was only 11, 12 and 13 for LCH?

      Hi LCstudent101,

      you are quite right, this was a mistake on my part. Thanks for querying it.

      The following is the situation:

      JCO - no theorem proofs required

      JCH - 4, 6, 9, 14, 19 proofs required

      LCO - no theorem proofs required

      LCH - 11, 12, 13 proofs required

      Note that for LCH:

      A knowledge of the Axioms, concepts, Theorems and Corollaries prescribed

      for JC-HL will be assumed.

      Students will study all the theorems and corollaries prescribed for LC-OL,

      but will not, in general, be asked to reproduce their proofs in examination.

      However, they may be asked to give proofs of the Theorems 11, 12, 13,

      concerning ratios, which lay the proper foundation for the proof of Pythagoras

      studied at JC, and for trigonometry.
