📐 2D Coordinate Geometry - Python OOP Project

This project demonstrates the core principles of Object-Oriented Programming (OOP) in Python using real-world mathematical applications from 2D Coordinate Geometry.

📚 Modules Covered

1. ✅ Point Class

• Represents a point in 2D space.
• Features:
  • Distance between two points
  • Midpoint
  • Slope between points
  • String representation using __str__ and __repr__
  • Operator overloading (==, <, >, etc.)

---

2. ✅ Line Class

• Represents a line segment defined by two points.
• Features:
  • Line equation in form y = mx + c
  • Slope and y-intercept calculation
  • Midpoint of the line
  • Check if a point lies on the line
  • Distance from a point to the line
  • Custom string formatting for equations

---

3. ✅ Circle Class

• Represents a circle in 2D space.
• Features:
  • Equation in standard and general form
  • Area and circumference calculation
  • Point containment check (inside, outside, or on circle)
  • Relation with another circle (touching, intersecting, etc.)
  • Optional visualization with matplotlib

---

4. ✅ Triangle Class

• Represents a triangle using three points.
• Features:
  • Area (using Heron’s Formula)
  • Perimeter
  • Centroid
  • Type classification (equilateral, isosceles, scalene, right-angled)

---

🔁 Unified Test File: zgeometry_test.py

• Demonstrates and tests functionality from all modules.
• Provides real-time outputs and comparisons using hardcoded examples.
• Acts as a reference for using each class and method.
