Hello welcome to the 'As it were' Maths YouTube Channel! I love maths and I am in the Sixth Form. The purpose of this channel is to help those of you out there who like maths as much as I do. Thanks and I hope you enjoy!

This particular proof is one that you will have to memorise for A level as it is a very common proof question. If you know the proof, then it is a question in which you can relax and just write down the proof whilst giving your mind a break. This will give you a real boost in an exam!
