Explore Trigonometry in a New Way Using Augmented Reality
The Interactive Excitement of AR Technology in a Feature Packed Learning Tool



Check out our Geometry Portal AR and Geometry AR for middle school and high school age students!


Bring the excitement of exploring trigonometry concepts right into your classroom or living room with the the Trigonometry Portal AR app.



Create virtual rooms filled with information about key terms and concepts from the high school trigonometry curriculum.

Explore trigonometry in a new way with the Trigonometry Portal AR. Use the camera view on your iPad to detect a flat surface and then tap the screen. Instantly a portal opens to a world filled with information about the terms and concepts that are part of the trigonometry curriculum.

Walk around in the augmented reality trigonometry portal. Tap on the walls and other objects in the rooms to get more information and to hear Siri read aloud information about the selected item. Scroll through a list of terms related to the rooms, walls and objects in the portal.

Trigonometry Portal AR creates virtual rooms that are approximately 4 meters by 7 meters. It is best used in a well-lit open space, perhaps in a school's auditorium or multi-purpose room.

Be sure that your iPad allows access to the camera function by choosing Settings -> General -> Restrictions -> Off.

Special features make using the Trigonometry Portal AR fun:

1. Explore virtual rooms filled with algebraic information.

2. Tap buttons, objects and walls, to learn to about the properties of real numbers other important concepts.

2. A fun way to encourage social interaction while learning and using Augmented Reality. Optionally the names of shapes and descriptions can be read aloud by the iPad.

3. Use AR technology to walk up to and around rooms exploring shapes to view from a different perspective.

4. Use synthesized speech to hear the names of the shapes and to learn about their properties.

5. Sound effects make the interaction even more fun.

6. Available exclusively for iPad devices.
