Geometry Ace
Geometry Ace is a fusion between a graphics based calculator and a geometry textbook.
Detailed stepbystep solutions update as you create new math problems by changing the graphics.
Learn vocabulary with unlimited examples.
Geometry Ace can be used by middle school and high school students as a math tutor for extra help.
Geometry Ace is a great tool for teachers to use in the classroom.
Points, Lines, Segments, Rays, Angles, Triangles, Quadrilaterals, Circles, Polygons
Dynamic Solutions

Geometry Ace does not simply calculate lengths and areas for you. It shows you stepbystep how to do it!

Detailed solutions update instantly as you change the graphics for a problem.

You are not limited to a set of prewritten or randomly generated problems. This allows you to investigate any “what if…” that comes to mind.
Dynamic Vocabulary

Learn vocabulary with unlimited examples and nonexamples.

Classifications and properties of geometric shapes light up as you create shapes that meet the definitions.

Easily view definitions with the tap of a finger.
Transformations

ROTATIONS, REFLECTIONS, and TRANSLATIONS.

Easily change degrees of rotation, center of rotation, line of reflection, and translation vector.

Point mapping is shown!

Make a copy of preimage and images so that successive transformations can be performed on the same object. Copies allow you to see previous steps.
Constructions

Includes points, lines, segments, circles, perpendicular lines, parallel lines, tangents, and angle bisectors.

Easily make attachments to points, lines, circles, intersections, and midpoints.
Algebra and Introductory Material

Includes necessary algebra topics needed for coordinate geometry such as finding slope and writing equations for lines.

Solutions are listed in fraction form (instead of decimals) whenever possible.

Includes introductory material such as how to find coordinates of a point.
Additional Features
Input Keypad
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 yintercepts. Use this to create equilateral triangles, 306090 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.
QuickStarts
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.
Load Reference Background Image
Use iPad camera to take a picture or load a picture from the iPad photo library.
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.
