I am sure many have seen this problem before, but Mathematics is never going to run out of things for us to spend more time looking at. I picked this up from a friend's daughter's homework they were asking me about. The problem has a couple of particular fascinations for me based on playing with it myself and putting it on my classroom door.
1. That there are some quite different ways to approach it
2. That there is significance difference between asking students or a particular unknown length and a more general 'given the diagram, what else can you tell me that is true?' approach
That last thought has occupied me for a while....
Here is another one!
This took even more thought! and even prompted +Simon Gregg to write this blog post when he first saw it!— Mr Noble (@MathsinP5) November 19, 2014
No solutions here as that would spoil the fun!
