This geocache is part of the Murweh Triangle Geoart. It is NOT at the published coordinates. To find the cache, you need to work through the following.
Geometry in maths was fun at school, because you could always do something practical to prove it. And it had practical applications.Take Builders Triangles. for example.
Builders use Pythagoras’ Theorem all the time.
Need a right angle fast?
Easy.
Make a 2,4,5 Triangle
Connect three lines:
• 3 long
• 4 long
• 5 long
And we get a right angle (90°)
So how does that work?
Over 2000 years ago there was an amazing discovery about triangles:
When a triangle has a right angle (90°) ...
... and squares are made on each of the three sides, ...
then the biggest square has the exact same area as the other two squares put together!
It is called "Pythagoras' Theorem" and can be written in one short equation:
a2 + b2 = c2
Pythagoras's Theorem can be easily demonstrated. Construct squares on each side of the triangle, as shown below. Then, the large squares can be subdivided into smaller squares, which can be counted to be the same quantity
And that’s a 3, 4, 5 triangle, too.

It looks really good in Lego:
