Where it wins
- Drag base elements to update dependent parts of a construction.
- Supports Euclidean, hyperbolic, and elliptic geometries.
- Includes automatic proving, loci, CindyLab simulations, and CindyScript.
Where it doesn't
- Its scope centers on construction and exploration rather than proof practice.
- Classroom and practice features are less extensive than some alternatives.
- Documentation references older updates, which may complicate onboarding.
Our verdict on Cinderella
Cinderella is interactive geometry software for students and teachers working at school or at home. It supports dynamic constructions: dragging base elements updates dependent elements, making relationships visible as a construction changes. Its range includes Euclidean, hyperbolic, and elliptic geometry, so it suits learners and educators who want to explore beyond standard plane geometry as well as create conventional constructions. The vendor says the software is free and that all features are available without licenses.
The standout depth is in construction and exploration. Cinderella can generate geometric loci, construct transformations and transformation groups, and produce automatic proving reports on nontrivial facts that arise during construction. CindyLab adds physical simulations, while CindyScript lets users extend constructions through scripting. Interactive web-page export offers a way to share constructions beyond the desktop software. This combination makes it a fit for advanced geometry work and exploratory lessons, rather than a narrowly focused diagramming tool.
The trade-off is that its platform and learning environment are less extensive than products with broader classroom or practice features. Cinderella does not emphasize proof practice, and its published documentation references older updates, which may matter to schools seeking current onboarding materials or structured student exercises. Its named platforms include Windows, macOS, Linux, and web, but the software's core positioning remains desktop-oriented. Choose Cinderella for free access to flexible constructions, non-Euclidean geometry, and supporting tools; look elsewhere if guided practice and a fuller classroom workflow are central requirements.
