What's New

- Added Drag-n-Drop Workspace Smart Tools for enhanced analysis of different models. Smart tools are intelligent drop and snap-to locations for line and circle intersections, perimeters, perpendicular, parallel, and tangent lines and points. Snap-to points, lines, and circles maintain context sensitive lockon state until specifically disconnected to allow long chains of dependently associated workspace tools that move according to the dependency relationship (parallel, perpendicular, radius, linked, midpoint, etc.) as defined by the user.
- Added a 25 step Undo and Redo for quick recovery of mis-steps as well as for replay
- Improved saving and loading of workspaces for quick, more relevant access
- Added new and improved existing export and import of the workspace environment
- Added reference “shape” indicators on shape specific slide out tabs
- Updated the menu color scheme and formatting layout

App Description

Interactive Geometry is a friendly, intuitive and easy-to-use math application for learning and teaching basic and advanced geometry skills and lessons. This application contains howto's for step-by-step learning and understanding of many key geometry concepts, a skills checker to test understanding, shape recognition indicators when special geometric shapes are created, and an interactive workspace sharing mode linking two or more iPads. Workspace smart tools have been added to give the user intelligent drag-n-drop marker points, lines, and circles that can be used to analyze shapes to visually calculate line midpoints, bisect angles and much more.

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 manipulated by dragging points and lines or by manually entering parameters associated with the given shape.

The interactive nature of the program allows the student to see and better understand relationships, math concepts, and properties of a geometric shape when they drag points in a geometric shape. You can interactively work with reflections, rotations, and translations of the shapes, freely or using reference points and lines.

Load reference images for display on the workspace background or take a snapshot (iPad 2 or newer) of an item around you for display in 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 properties such as angles, lengths, slopes, and more can be viewed using the "Props" slide out view or by touching on the labels associated with the points and lines of each shape.
