## What is Rachii Geometry?

Turn your iPhone or iPad into a space for exploring geometric construction. Rachii Geometry places illustrated compasses, rulers, protractors and set squares on your canvas. Draw with your finger, or Apple Pencil on a compatible iPad.

CONSTRUCT WITH VISIBLE INSTRUMENTS
• Set and lock the compass radius, draw circles and arcs, swap its needle and drawing tip, and choose solid or dashed lines.
• Use a pen along a ruler or set-square edge. Snap the ruler parallel or perpendicular to existing lines.
• Measure angles with a 180° or 360° protractor that snaps to vertices and lines.

CREATE AND EDIT
• Name points and snap them to nearby lines and intersections.
• Insert 48 figure templates: angles, triangles, quadrilaterals, polygons, circles, ellipses, solid wireframes and nets.
• Set custom angles from 1 to 360 degrees, including decimals.
• Select several objects to move, resize, recolor or delete together.
• Erase just the area you rub, with undo and redo.

KEEP AND SHARE YOUR WORK
• Worksheets save on your device. Open earlier work from the library and restore worksheets from Trash.
• A fresh launch starts with a blank canvas while keeping previous worksheets.
• Export PDF, PNG or editable .rachiigeo backup files.
• Explore equilateral-triangle and perpendicular-bisector examples and review construction steps.

Requires iOS/iPadOS 17 or later. Up to 500 objects per worksheet; imported backups up to 20 MB. Solid figures are 2D wireframes. Objects do not maintain dynamic geometry constraints. The app does not automatically sync worksheets across devices.
