Today at maths time, one of the groups was learning about Pythagoras' theorem to a deeper level.
Firstly, we learnt that several civilisations (Babylonian, Indian and Chinese) appear to have known about the relationship between the sides in a right-angled triangle before Pythagoras (c.859 - c.800 BC). It is believed Pythagoras may have been the first to prove it, but we cannot be sure because he wouldn't allow people to write down any of his teachings.
So what is the Pythagorean Theorem?

We then used our algebra skills to use the formula to solve problems when we already knew the hypotenuse (c), but want to work out either a or b. Here's how we did it:
The next step for the group will be looking at practical applications for the theorem (which is used a lot in 'real life'). To do this, students will be completing this webquest.
