GeoGebra 3D with AR (iOS): Quick Setup Instructions
WHAT TO DO:
1) Here's the link to GeoGebra 3D Calculator on AppStore. Install it on your iOS device.
2) Once it's installed, open the app. Use the app to create any 3D solid.
Here, we simply created a sphere by using the SPHERE WITH CENTER THROUGH POINT 
tool.
(This tool is the 5th one in on the left on the top row in the pic below).
tool.
(This tool is the 5th one in on the left on the top row in the pic below).
3) Next, press the AR button (lower right within 3D Graphics pane). You'll see everything disappear and you'll see your environment on the screen. Move your device slowly, making sure to AIM IT AT THE FLOOR. Wait a few seconds. Look for a SQUARE to appear. Once you see it, touch anywhere on the screen to place the object in your environment.
Use your fingers to reposition the objects. KEY IS TO MOVE SLOWLY.
Have fun exploring!
4) Press the 3D button (lower right) to exit AR view.

Geometry Demos with Resource Links: GeoGebra 3D with AR (iOS)
Below is a list of quick screencasts that illustrate how GeoGebra 3D with Augmented Reality (AR) can provide both teachers and students an ACTIVE, HANDS-ON approach to exploring some geometry concepts.
Enjoy!
All screencasts shown here were recorded on an iPadPro (larger screen) or iPhone10sMax (smaller screen).
EXPLORING SURFACE AREA OF A RECTANGULAR PRISM

FINDING THE DIAGONAL OF A RECTANGULAR PRISM: BIG HINT
Link to GeoGebra resource shown above can be found here.
MODIFIABLE TRIANGULAR PRISM STUDENTS CAN EXPLORE
Link to the GeoGebra resource shown above can be found here.
ANATOMY OF A SQUARE PYRAMID
Link to GeoGebra resource shown above can be found here.
Cone and Cylinder AR Modeling Challenge
In the screencast below, both the cylinder and cone have equal radii and equal heights.
The height of each is double the radius.
Their circular bases are tangent to each other.
How can we construct this 3d image in GeoGebra 3D Graphing Calculator on your device?
Try to do so, and then project what you create in Augmented Reality.
If you're up for it, you can find such solids or create them from cardstock and put them to the "AR TEST" as shown in the screencast below.
How well do the virtual images place when superimposed on top of the real world objects?
Quick Demo
Season Changes: Sun-Earth Demo
Even though the Sun and Earth are not constructed to scale (nor is the distance between the centers of these two masses) , the Earth (shown here as northern hemisphere and southern hemisphere) does have an axis that is tilted approximately 23.5 degrees about its center with respect to the line that is perpendicular to the plane containing its orbit.
1.
For the hemisphere in which you live, what Sun-Earth event does point A represent?
What does point B represent? What about point C? What about point D?
Give reasons for your responses.

Conic Sections: Introduction
Explore with this app for a bit. Then use it to help answer the thinking questions that follow.
1.
Note the equation of the plane is z = some constant. Change the equation of this yellow plane to z = 2.
Then change it to z = 1.
Then change it to z = 4.
How would you describe the intersection of this plane and double-napped cone?

Shortest Path Between 2 Points on a Sphere
In the context of a SPHERE,
A GREAT CIRCLE is defined to be a CIRCLE that lies on the SURFACE OF THE SPHERE and LIES ON A PLANE that PASSES THROUGH THE CIRCLE's CENTER. In essence, the center of a GREAT CIRCLE and the center of the sphere are the same.
Consequently, a GREAT CIRCLE also the largest possible circle one can draw on a sphere.
In the applet below, the pink arc and blue arc make up a GREAT CIRCLE.
To explore this resource in Augmented Reality, see the directions below the applet.
1.
Note that the black arc and yellow arc (put together) DO NOT make a great circle. Why is this?

Directions:
Move the 2 WHITE POINTS anywhere you'd like on the sphere. The PINK ARC is part of a GREAT CIRCLE of this SPHERE. You can move the YELLOW POINT anywhere you'd like as well.
Again, note that the YELLOW ARC is NOT PART of a great circle.
Slide the slider slowly and carefully observe what happens.
2.
How would you describe the SHORTEST DISTANCE between 2 POINTS along a SPHERE? Explain.
