Geometry editor
Draw geometric constructions alongside equations, text and diagrams.
How to use this editor
Use the selected geometry tool and choose a construction in its controls. Click the canvas to place its points.
This is an unsaved scratch canvas. It does not change your saved canvases. Copy any work you want to keep before leaving this page.
What you can make
Create and edit your own canvas object.
What to know
Construction tools are interactive drawings, not an automatic geometry theorem prover.
Mathlean combines visual mathematical input with computation and canvas tools. Results depend on the expression and available engine support; check important answers independently.
