What's New

---All New Collaboration Feature for Multiple iPads---
New interactive collaboration mode provides sharing of the application workspace between a teacher and a student or between students working together on a task. The multi-viewing mode allows teachers to simultaneously view the workspace of up to 30 students at a time. This collaboration mode supports two or more iPads running Interactive Geometry on a local wireless network.
---
- Added quick switching for left and right menus
- Added separate breakout tabs for HowTo, Skills, Stats, Terms, and Help screens
- Added axis position reference lines to more quickly help the user identify their location on the grid when dragging a shape point.
- Fixed several bugs in the previous version and increased the displayed values for some labels.

App Description

Interactive Geometry is a friendly, intuitive and easy-to-use math application for teaching and understanding basic and advanced geometry related skills and lessons. This application contains howto's for step-by-step learning and understanding of many key math concepts, a skills checker to help track your understanding of the material, shape recognition indicators when special shapes and conditions are created, and an interactive workspace sharing mode between iPads.

This application is used in the classroom and at home to learn and understand basic and complex math equations and skills associated with points, lines, rays, segments, single and pair of angles, triangles, quadrilaterals, ellipses, circles and more. These geometric shapes can be changed by dragging points/shapes or by manually entering parameters associated with the given shape.

The interactive nature of the program allows the student to see and better understand math concepts, relationships, and properties of a geometric shape when they dynamically move points on the shape. You can show and define point and shape reflections across a reference line, move points freely, rotate points about a reference point, and move points linearly (translate) parallel to a reference line.

This program is used as a tool to compare and measure the length, slope, angles, and areas of objects located in reference images displayed on the background. Load images for display on the background or take a snapshot (iPad 2 or newer) of an item around you for display on the background. You can then select the line segment, angle or other shapes to measure lengths, angles, and areas of the items in the background image. Shape stats such as angles, lengths, slopes, and more can be viewed using the stats screen or by touching on the labels associated with the points and lines of each shape.
