Does anyone know what theorems you need to learn and any website on where i can find them
I have them in my maths book, I can send you a picture of them if you'd like
Here is a link to a website with all the proofs and theorems, learn the first five theorems on this, you don't have to know how to prove them but you do have to know how to apply them, and then scroll about half way down the page and you will see proof of five theorems, you have to know how to prove all of them because any one of them can come in the exam. http://www.projectmaths.ie/for-students/junior-certificate/
