In case my previous musings on lego triangles weren’t geeky enough for you, here’s some more. 60 degree 3-7-8 / 5-7-8 math In my prior note I pointed out that you could construct an exact 60 degree angle with a 3-7-8 or 5-7-8 construction, such as this one: The blue technic beam is the “7”…

Time for some fun with Pythagoras! Lego tends towards rectangular constructs, but sometimes we might want to make triangular connections. Technic beams especially lend themselves to this. Right-angled pythagorean triangles are fairly easy to construct. Here’s a 3,4,5 triangle: Notice that when you build it you build it as 4,5,6. That’s because it’s the distance…
