The goal of this GeoGebra Augmented Reality modeling challenge is to author 2 surface equations (with domain restrictions) to [b]construct a [color=#1e84cc]REGULAR [/color][color=#ff00ff]OCTAHEDRON [/color]!!! [/b][br][br]A regular octahedron is one of the 5 main platonic solids. [br]A regular octahedron is made up of 8 faces. [br][b]Each face is an equilateral triangle. [/b][br][br][b]Modeling Clues:[/b][br][br]Even though there are infinitely many ways to position & size this regular octahedron, for the one in this screencast (below):[br][br]1) (0,0,0) serves as its center. [br][br]2) Each edge (side of any equilateral triangle) is 6 units long.
