Isoceles – Geometry Sketchpad

Taking geometry this year? Isosceles is here to help!

Fresh and easy to use, Isosceles is the perfect drawing tool for geometry students and teachers.

In this free version, you can create and manage 2 sketches. Upgrade to Isosceles+ within the app to create unlimited sketches, sync with iCloud, draw isometric sketches, and more.

FEATURES:

Simple, versatile drawing tools

• Includes tools for creating lines, circles, and polygons.
• The compass tool lets you create myriad constructions from angle bisectors to spirals.
• Isosceles automatically snaps new additions to nearby objects, keeping your drawing accurate so you can focus on the construction.
• Draw perpendicular bisectors, angle bisectors, altitudes, and other constructions that automatically stay snapped together.
• Toggle between heavy and light pencils to bring out the important parts of the drawing. Change the stroke and fill color of figures.
• Add text annotations anywhere in the drawing.
• Three distinct modes (Classical, Cartesian, and, for Isosceles+ users, Isometric) that change settings quickly and easily to fit any kind of drawing.

Measure objects easily

• View and edit information about any object, such as the length of a line or the circumference of a circle.
• Add marks to show congruency and parallel objects, extend lines, show live measurements, and more.

Tools for students and teachers

• Isosceles features a handy notes sidebar so students can type notes during class without leaving the app. Teachers could use this feature to jot down notes to introduce while teaching.
• Connect your iPhone (4 or later) or iPad to a TV or projector to present class material.
• Put together homework assignments quickly by constructing diagrams with Isosceles.

Isosceles was designed and developed by a 14-year-old.
