J For Japanese Theorem (A To Z Challenge)

Well this is embarassing... I must non know my alphabet!  I accidentally skipped J.  I intend I was hence excited to practise my giveaway alongside my kidsmathteacher every bit the K that I repressed my cognition of the alphabet : )

Make certain to larn inwards my giveaway that I posted close yesterday alongside 3 nifty prizes!

For a existent stretch for simple schoolhouse kids y'all tin ship away demo them that at that topographic point are problems that cause got multiple steps to solve--theorems.  A occupation alongside all the steps completed brand upwards a theorem.  There is a theorem inwards geometry called the 'Japanese Theorem' (Thanks Wolfram mathworld for having an alphabetical glossary in addition to explaining things simply).

This theorem states that if y'all draw the same circle but brand triangles inwards the interior inwards whatever manner, hence draw incircles to those triangles, the total of the interior radiuses volition ever live on the same (even if your triangles don't await the same every bit the others).

It is pretty neat!  I tried to brand my own, but making the incircles is harder than y'all mightiness intend to brand certain it barely touches.  I intend these await pretty neat in addition to fifty-fifty inwards kids don't know precisely how to practise it, just seeing this makes y'all curious to a greater extent than close math, right?

'Til Monday!  Have a nifty weekend!
