A minimalist geometric drawing and calculation tool designed for students, teachers, and designers. Create precise 2D shapes with an intuitive, clean interface, while enjoying automatic dimension calculations and step-by-step derivations.
Key Features
Dual Drawing Modes: Generate standard shapes via precise parameter input or create freeform designs by dragging vertices—with data updating in real-time.
Comprehensive Shape Library: Includes standard polygons, regular polygons (3–20 sides), circles, ellipses, sectors, arcs, circular segments, annuli, and more.
Teaching Aids: Instantly display altitudes, medians, angle bisectors, perpendicular bisectors, incircles/circumcircles, axes of symmetry, and coordinate grids to support learning.
Robust Calculation Engine: Automatically calculates perimeters, areas, angles, arc lengths, and side lengths; provides step-by-step solutions and allows one-tap toggling between decimals and fractions.
Coordinate Geometry System: Cartesian coordinate canvas supports calculations for vertex distances, midpoints, and slopes—ideal for coordinate geometry exercises.
Customizable Canvas: Choose from various paper backgrounds; adjust colors and line weights for lines and annotations; supports zooming, panning, undoing, and resetting.
Local Saving & Export: Automatically saves drawing history for continued editing; export as high-resolution PNGs for assignments, lesson planning, or creative projects.
Focus on the geometry itself—ensuring every drawing is backed by precise calculations and clear visuals.
