Conic Section Rulers (Ellipse, Parabola, Hyperbola)

A set of three drawing rulers for the conic sections: ellipse, parabola and hyperbola. Cheaper than buying them, and you can scale them in the slicer.

Design by xprees on Printables, shared under CC BY 4.0. The files and photos are the designer's, unchanged.

1. Print the three rulers flat.
2. Students draw each curve and mark its focus and directrix (or foci).
3. Find the curves in the real world: orbits, a thrown ball, a cooling tower.
