A track for each stage of school
From shape recognition to high school demonstrations, plane geometry grows in layers. Choose your level: each has short lessons, draggable pictures, and responsive challenges.
Choose your track
| Trail | What will we discover | First step |
|---|---|---|
| 🌱 Elementary I · 1st to 5th year | Flat shapes, lines, spins, polygons, symmetry, perimeter and area in the mesh | Start exploring |
| 🚀 Elementary II · 6th to 9th grade | Point, line and plane, angles, triangles, parallels, quadrilaterals, polygons, circumference, constructions, areas and Pythagoras | Investigate the figures |
| 🎓 High School · 1st to 3rd grade | Notable points, angles on the circumference, Thales, similarity, right triangles and any, regular polygons and areas | Demonstrate and calculate |
Your pace counts. The years indicate a suggested route. Return to a track to review or move forward when you can explain in your own words why each result is worth it.
The interactive book
The Elementary II and High School chapters form the interactive Flat Geometry book: theory organized into definitions, postulates and theorems, figures to drag, exercises with answers and entrance exams.
