Displaying a Triangle Grid

Displaying a grid of triangles in Ruby

Displaying a grid of equilateral triangles turns out to be really straightforward. We won’t go over the derivation itself here, but we’ll walk through the resulting measurements, and then we’ll implement it all in code.

Because we’re working with equilateral triangles, we know that each side is the same length ($s$). Furthermore, geometry tells us that the height of an equilateral triangle is $s$ ...
