In this challenge, we see 4 surfaces that join perfectly together.
How can we reconstruct this surface within GeoGebra Augmented Reality?
units away from its center. The entire conjugate axis of this described hyperbola would be 2 units long.
The units away from its center. The entire conjugate axis of this described hyperbola would be 2 units long.

**Clues:**The**blue surfaces**are parts of infinitely long hyperbolic sheets. The cross section of this infinitely long surface withany plane parallel to the plane y = 0 is a hyperbola with foci located**pink surfaces**are parts of infinitely long hyperbolic sheets.
