Couldn't this be a square pyramid? A square bottom with 4 right angles, and 4 triangles meeting at a single point with 180 degrees, or two right triangles each. This means \(4+4*2=12\) right angles. Also, we would then have 8 edges. 4 on the square, and 4 more joining at the tip. So you would have 8 edges.
