| Jul 12, 2019 at 16:45 | comment | added | hexomino | @Moti No additional faces needed. The four faces as cut can be joined together to form a right-angled pyramid exactly as you've described. | |
| Jul 12, 2019 at 16:33 | comment | added | Moti | I am seeking a solution where three faces are perpendicular to each other - three edges are along the cartesian axes and 4 faces (I think your solution contains a face that is not a piece of the cut) | |
| Jul 12, 2019 at 16:21 | comment | added | hexomino | @Moti The pyramid in our solutions is a right-angled pyramid then. If you consider any of the right-angled triangles as the base, the apex will lie above one of the vertices of the base. | |
| Jul 12, 2019 at 15:00 | comment | added | Moti | No. Use this definition: " A right-angled pyramid has its apex above an edge or vertex of the base. In a tetrahedron these qualifiers change based on which face is considered the base" and the requirement is - apes above a vertex. | |
| Jul 12, 2019 at 12:04 | comment | added | Showsni | I assume the question means a right pyramid, rather than right angled. A right pyramid has the apex directly above the centre of the base. | |
| Jul 12, 2019 at 8:52 | comment | added | hexomino | What's the definition of a right angle pyramid? | |
