Describe your change:

This PR adds several enhancements and new capabilities to the geometry module:

  • Add Angle.to_radians() and Angle.from_radians() conversions
  • Improve Ellipse.perimeter using Ramanujan’s approximation and add eccentricity property
  • Extend Polygon with:
    • get_vertices() to compute vertex coordinates
    • perimeter() and area() methods
  • Update Rectangle to build all 4 sides and integrate with the polygon logic
  • Introduce Triangle class:
    • Validate side lengths (triangle inequality)
    • Compute interior angles (if not provided)
    • Compute perimeter and area (Heron’s formula)
  • Add and adjust doctests for accuracy and coverage

These improvements expand the geometry module’s ability to model and calculate advanced shapes.

  • Add an algorithm?
  • Fix a bug or typo in an existing algorithm?
  • Add or change doctests? -- Note: Please avoid changing both code and tests in a single pull request.
  • Documentation change?

Checklist:

  • I have read CONTRIBUTING.md.
  • This pull request is all my own work -- I have not plagiarized.
  • I know that pull requests will not be merged if they fail the automated tests.
  • This PR only changes one algorithm file. To ease review, please open separate PRs for separate algorithms.
  • All new Python files are placed inside an existing directory.
  • All filenames are in all lowercase characters with no spaces or dashes.
  • All functions and variable names follow Python naming conventions.
  • All function parameters and return values are annotated with Python type hints.
  • All functions have doctests that pass the automated testing.
  • All new algorithms include at least one URL that points to Wikipedia or another similar explanation.
  • If this pull request resolves one or more open issues then the description above includes the issue number(s) with a closing keyword: "Fixes #ISSUE-NUMBER".

…geometry, and triangle class

- Added `Angle.to_radians()` and `Angle.from_radians()` for degree-radian conversion.
- Improved `Ellipse.perimeter` with Ramanujan’s approximation and added `eccentricity` property.
- Enhanced `Polygon` with vertex generation, perimeter, and area computation.
- Updated `Rectangle` to construct all four sides and support complete vertex/area logic.
- Introduced new `Triangle` class with validation, perimeter, and Heron’s area formula.
