Maths - Constructions

    Do we need to know all of them by heart? Is there a specific number or range of constructions we need to know?
    Is there a chance that they will not come up in OL?

    Do we get a choice between theorems and constructions?

    my teacher told us just to learn the construction and never mentioned anything about theorems so i'm guessing we do have a choice. However there is people on here saying we've to know both so i'm just really confused by it all now -not what you wan't the day before the exam:pac:

    Assuming you are talking about HL, Q6 will have a choice but it there may not be a construction so you may have to prove something. Have you not looked at the sample paper?

    Will I chance just learning the constructions? I'm looking for an A so I don't want to throw it all away just cause I thought I didn't need to know any theorems

    Learn the theorems tbh! Both a construction and a theorem came up last year as far as I remember.

    Don't be an idiot, there are only 3 theorems just learn them. It could be 25 marks (4%) you're throwing away. Have you looked at last yrs p2?!

    Last year it was a construction or theorem for OL..what 3 theorems are there for OL?

    I'm pretty sure it's a choice, you do either A or B of the question.

    You do not have to prove the 3 theorems for OL, just know how to use them. Just learn the constructions. Some of the constructions are done on this website:

    does that mean there are only 2 less constructions to be learned for OL?

    In HL there's definitely a choice between Constructions and Proofs. Our teacher didn't bother with proofs at all and did a bit on constructions. Constructions are very straight forward. Handy if you do DCG!

    There wasn't a choice on the mock and isn't a choice in pretty much all the sample papers.

    I don't get how teachers can say that because on last year's paper there was very clearly a theorem and a construction and no choice (other than 6B). :confused:
