Angle & Length

iPad / Education

Angle & Length App was originally envisioned as a tool to assist some people on the Autistic Spectrum with learning about angles, lengths and sequential steps in creating shapes out of lines.

Angle & Length App allows a user to try to make shapes from up to twenty three straight lines. Each line can be of varying length and the angle between each line can be from 0 to 359 degrees.

Each shape can be viewed as an animated drawing. Where the shape is consecutively drawn from each line and each line is gradually drawn in sequential order.

Angle & Length App is pre-loaded with four user editable shapes plus another four shapes to be created by a user.


Angle & Length App builds upon concepts introduced in the Numbercus App.
