Raj Manoj Patil — R23-T036: Teach the idea behind maths/ear_clipping_polygon_triangulation.py #38

Student: Raj Manoj Patil

Task: R23-T036 · 6 of 10
Repository: https://github.com/S-AI-Projects/TheAlgorithms-Python
Assigned working branch: student/e26b07f0759

Goal

Write an explanation good enough for a classmate to re-implement the algorithm, and improve the file's own documentation. Experiment: triangulate 3 polygons (convex, concave, star-shaped) and draw the triangles with matplotlib.

Steps

1. Write work/R23-T036/EXPLAINER.md: the idea, a worked example by hand, and a diagram.
2. Add or improve the module docstring with a reference link (CONTRIBUTING.md asks for one) and a one-paragraph summary.
3. Carry out the experiment described in the goal and include the result.
4. Ask a classmate to re-derive one doctest result from your explainer and record their feedback.
5. Make the code change in the repository: maths/ear_clipping_polygon_triangulation.py: module docstring with reference and a worked doctest on a small concave polygon. Re-run the automated check and the repo's own tests afterwards.
6. Prepare the PR: on branch R23-T036, commit the code change plus your work/R23-T036/ evidence, put your findings in the PR description and open the PR against the org fork. For a later upstream PR, create a second branch containing only the code change (no work/ folder).

Done when

☐ EXPLAINER.md triangulates a convex, a concave and a star-shaped polygon with matplotlib figures.
☐ maths/ear_clipping_polygon_triangulation.py module docstring gains a reference link and a worked doctest on a small concave polygon (e.g. 5 vertices) checking n − 2 triangles.
☐ Existing 21 doctests pass.
