I've got my exams next year, and can some one please help me with Pythagoras' Theorem? I get the a x b = c2, but not the dividing part. Can you please help?

If your going into year 9
You dont have sats anymore

It's Pretty Simple Actually. I did struggle with it when I was younger. It Basically states that the sums of the two smaller sides of a Triangle Squared(The Adjacent and the Oppisite Side's) Should Equal the sum of the biggest side Squared(the Hypotonuce). So A squared+ O squared= H squared.
Here's a Simple sum for you fainter.
If O=3 and A=4. Find X using Pythagoreous theorm.
Step 1. Square Everything Available. So 3 squared+ 4 squared= X squared.
Step 2. Break Down. 9+16= X squared
25= X squared.
If 25 equals X squared then X should equal the Square root of 25.
So Square root of 25= 5.
Hope this helps.

You should understand it. Great description. Cuddles (Except if your not finding the hypotenuse. Instead of adding you take.) |

No, to find the Hypotenuse you do A2+B2=C2 then find the Square root of C2

No, to find the Hypotenuse you do A 2+B 2=C 2 then find the Square root of C 2I meant it as if you alread had the hypotenuse and you have to find o or a you take instead. |

Yeah. Well I suck at most other things but I am awsome at Pythagoras' Theorem

Im like that to
But i suck at everything except algebra.
Its weird im good at the harder stuff but bad at the simple stuff.
