I've only recently moved to OL maths , what proofs or constructions am I supposed to know? Thanks
no proofs needed as thats a one or the other question, mainly incircle, circumcircle, centroid and parallelogram
No theorem proofs.
Constructions: 1 to 21 inclusive (i.e. all the JC ones plus the additional LCO ones).
