• #### HELP!!!!!!!!! lukewynne15

I have no clue on how to do Pythagoras theorem. I have read true the chapter in my book and looked true notes that I have, however I just cant remember doing it in 1st or 2nd year

1. #### examtips

its a squared plus b squared = to c squared c is the longest side

2. #### examtips

you apply this when a tiangle has two sides !

3. #### 11ND - CCM

^What sort of triangle has two sides??

Also, I think he is talking about the proof of this theorem. If so, it is probably the hardest one and there are several methods of proving it. I can't really help on this, and I don't know any links for a website. But if you have a form of it infront of you, the only real way to learn it is rote learning and trying to learn it off by heart and write it out.

I don't know much more beyond that but I hope it helps and good luck!!
