Pythagoras' Theorem

This PowerPoint was used to introduce Pythagoras’ Theorem to Functional Skills college students whose main course work is to do with the Building Trades (Carpenters, Electricians). The last 4 slides therefore deal with using Pythagoras’ theorem to calculate the length of roof rafters.

Editor’s note
I realise that using Pythagoras’ theorem is beyond the scope of L2 Functional Maths Exams but this is a very useful PPT due to the vocational questions. Would also be useful for GCSE Maths.
