Regulus (geometry)

Regulus is a fancy word that means a shape or figure in geometry that has a special and specific set of rules. Imagine you have a set of building blocks, like LEGOs, and you want to build something really cool and specific. In geometry, regulus is like a set of instructions or rules to follow to make a specific design. These rules tell you exactly where to put each block, how many blocks to use, and what angles to make between them. The end result is a very special and unique shape that follows these rules exactly. So, in short, regulus is a set of rules for building a very specific shape in geometry.
