✨ Overview
----------

[](#-overview)

`Sobhanmohammadi\Geometry` is a modern PHP geometry library designed for:

- 📏 Accurate geometric calculations
- 🧮 CAS-powered algebra evaluation
- 🎯 Configurable precision handling
- 🔄 Unit conversion
- 🧠 Step-by-step mathematical explanations
- 🧩 Extensible shape architecture

Unlike traditional geometry libraries, formulas are not manually calculated inside shapes. All algebraic operations are delegated through a dedicated CAS gateway.
