Hi i just dropped down to ordinary level maths and Im wondering what theorems i need to know :)

Racheldonnellan
you need to know theorems 1  21

themathstutor.ie
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 JCHL will be assumed.
Students will study all the theorems and corollaries prescribed for LCOL,
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.
