 # Algebra and Introductory Material

• ## Includes introductory material such as how to find coordinates of a point.

Menus allow for keypad entry of primary shapes which would be difficult to create by dragging the points in the workspace. Define the primary shape under study by entering points, angles, lengths, slopes, and y-intercepts. Use this to create equilateral triangles, 30-60-90 triangles, etc.

Teacher Mode
Allows teachers to monitor and interact with students who are on the same local wifi network and are running this app.

Quick-Starts
Allow teachers to quickly get all students on the same page with the same settings.

Skills Checks
Designed for students learning vocabulary. Skills are checked off as the student changes the primary shape to meet various requirements.

Save and Export or Import Files
Eight internal save spots are provided for each primary shape workspace. Additionally, the workspace configuration can be saved to, or imported from, the clipboard or email.
