Rozenn and Pythagoras

Rozenn's dad had shown her Pythagoras' Theorem at home, and she brought it in and explained it to us!

This is normally something children do in secondary school, but we got some idea of what it was all about.

In the picture there's a right angle triangle. We know two of the sides - in this case the shorter sides are 3 long and 4 long. We want to find out the length of the longs side.

Here's Rozenn explaining it:

And here are the Cuisenaire rods we used to help understand it better:

Mr Gregg was particularly pleased that Rozenn learnt about this because it's one of his favourite bits of mathematics!
