Geometry Ace: Math Tutor5.0.14 - App Store

Geometry Ace is a fusion between a graphics based calculator and a geometry textbook. Detailed step-by-step solutions update as you create new math problems by changing the graphics. Learn vocabulary with unlimited examples. Points, Lines, Segments, Rays, Angles, Triangles, Quadrilaterals, Polygons, and Circles. Transformations and Constructions. Full functionality with no ads or in-app purchases. Great classroom or home resource for elementary, middle, and high school students and teachers.

*** Easy Start-up ***
. Simply choose shape to study.
. Shape will already be on the screen and all you have to do is start manipulating it.
. Learn vocabulary, choose from list of tutorials, perform transformations, or create a construction.

*** Detailed problem solutions update as you change the graphics. ***
. You are not limited to a set of pre-written or randomly generated problems.
. Tutorial examples: finding the length of a line segment, finding the area of any type of quadrilateral, calculating the length of an arc, and many more.
. Geometry Ace does not simply calculate lengths and areas for you. It shows you step-by-step how to do it!

*** Includes introductory material and makes connections with algebra. ***
. Introductory material appropriate for upper elementary students is included.
. Helps with differentiation. Middle and high school students who need a refresher can review introductory topics.
. Algebra topics needed for coordinate geometry are included.
. Introductory topics include coordinates of a point, slope, and the equation of a line.
. Answers to problems are given in fraction form when possible.
. Solutions address common student misconceptions and give attention to detail.

*** Interactive definitions ***
. Relevant definitions highlight interactively as you drag points and lines to change the shape on the screen to meet various attributes.
. Example: A triangle can be obtuse, oblique, and scalene.
. Example: A polygon can be concave and irregular.
. Definitions are inclusive. Example: A quadrilateral that is a rectangle is also a parallelogram and a trapezoid.

*** Transformations: Rotations, Reflections, and Translations ***
. Easily change degrees of rotation, center of rotation, line of reflection, and translation vector.
. Point mapping is shown!
. Perform successive transformations on the same object.

*** Constructions ***
. Includes points, lines, segments, circles, perpendicular lines, parallel lines, tangents, and angle bisectors.
. Easily make attachments to points, lines, circles, intersections, and midpoints.

*** Monitor Students ***
. Teachers can view student’s iPad screens who are on the same local wifi network and running this app.

Version History Minor updates. 5.0.14 02/26/2018 Geometry Ace 5.0 is a complete overhaul of its predecessor app, Interactive Geometry (InGeometry). Definitions and tutorial problem solutions have been completely rewritten so they are easy to follow for middle and high school students. The touch interface has been greatly improved to work more smoothly. The user interface is more intuitive and an extensive help document is easily accessible within the app. Transformation tools now have easy to use dials and sliders for exact rotations and translations. Construction tools have been completely reworked to provide easier placement and attachments. More topics have been added. 5.0.6 03/20/2017 Geometry Ace 5.0 is a complete overhaul of its predecessor app, Interactive Geometry (InGeometry). Definitions and tutorial problem solutions have been completely rewritten so they are easy to follow for middle and high school students. The touch interface has been greatly improved to work more smoothly. The user interface is more intuitive and an extensive help document is easily accessible within the app. Transformation tools now have easy to use dials and sliders for exact rotations and translations. Construction tools have been completely reworked to provide easier placement and attachments. More topics have been added. 5.0 02/22/2017 - 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 4.0 05/02/2015 Improved HowTo content and formatting for all shape categories.
Fixed known errors. 3.6 01/07/2015 Updated menus and layout. Removed bottom menu.
Added category for learning/teaching transversal lines.
Added ability to edit and paste (import) point data for saved shapes.
Enhanced the workspace sharing mode fixed lock issue when switching screens.
Fixed other various bugs and errors. 3.5 11/12/2014 ---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.
