7. Three-Dimensional Geometry

• Three-Dimensional Shapes: Prisms, pyramids, spheres, and cylinders.
• Surface Area and Volume: Calculations for various 3D shapes.

2. Angles and Measurements

• Types of Angles: Acute, right, obtuse, straight, and reflex angles.
• Angle Measurements: Degrees, radians, and gradians.

Beyond High School: Advanced Topics

While the core curriculum targets grades 8–11, a comprehensive site often spills into pre-calculus and analytic geometry. Keep an eye out for sections covering: geometry-lessons.github.io

• Coordinate Geometry: Distance formula, midpoint, slope, and partitioning segments.
• Transformations: Rotation, reflection, translation, and dilation as functions on the Cartesian plane.
• Solid Geometry & Euler’s Formula: $V - E + F = 2$ for convex polyhedra.
• Introduction to Vectors: Geometric representation of magnitude and direction.

If these exist on geometry-lessons.github.io, they are likely presented with the same clarity: text, diagram, proof, practice.

6. Coordinate Geometry

When algebra meets geometry – distance, midpoint, slope, and equations of lines and circles.

Where Euclid Meets the Web: The Elegant Revolution of Geometry-Lessons.github.io

In an era of gamified learning apps and subscription-based courseware, a quiet, open-source project is proving that the best way to teach geometry is with code, not cartoons.

By [Your Name]

For generations, the geometry classroom was a static place. It was a world of compasses, protractors, and diagrams printed on paper—frozen images that asked students to imagine movement in stillness. A circle was drawn, and it stayed there. A triangle was defined, and it never changed.

But mathematics is not static. It is dynamic, fluid, and alive.

Enter geometry-lessons.github.io, an open-source repository and web application that represents a quiet paradigm shift in mathematics education. Hosted on GitHub Pages, this project strips away the clutter of modern EdTech to focus on a singular, powerful truth: geometry is best understood when you can play with it.

What You’ll Find Here

The site is built around one simple idea – geometry should be visual and logical. Every lesson includes: Title: Why Geometry Still Needs a Home on

• Step-by-step proofs (from triangle congruence to circle theorems)
• Interactive diagrams (where possible, using GeoGebra or JSXGraph)
• Practice problems with hints, not just answers
• Real-world connections (tiling, art, architecture, navigation)

The Community Aspect: Contributing to the Lessons

One of the most powerful, under-discussed features of the github.io ecosystem is forking. If you find a mistake in the lesson on the Law of Cosines, you don't just complain—you fix it.

Advanced users can visit the GitHub repository (remove the http:// part of the URL to find the repo) and:

1. Open an "Issue" to report a broken diagram.
2. "Fork" the repository to your own GitHub account.
3. Edit the Markdown or HTML file to correct the error.
4. Submit a "Pull Request" to the original author.

This transforms the user from a passive consumer into an active contributor. Over time, geometry-lessons.github.io isn't just a website; it's a living textbook maintained by a global community of geometry lovers.
