From SSS (Side-Side-Side) to HL (Hypotenuse-Leg), the site offers interactive diagrams where you can drag vertices to see if two triangles remain congruent under different transformations. 4. Circles and Coordinate Geometry

The lessons are designed to be sequential. Ensure you fully understand "Parallel Lines and Transversals" before moving on to "Quadrilaterals."
Whether you are a high school student or someone looking to brush up on the basics, the site covers the foundational pillars of Euclidean geometry. 1. Points, Lines, and Planes
