A solid shape made out of eight equilateral triangles is called a triangular bipyramid. This polyhedron consists of two triangular pyramids (tetrahedra) joined at their bases, creating a three-dimensional figure with eight triangular faces, six edges, and four vertices. The symmetry and uniformity of the equilateral triangles give it a distinct geometric shape.
What else can I help you with?
Why cant i build a platonic solid where 6 equilateral triangles meet at each vertex?
You cannot build a platonic solid with six equilateral triangles meeting at each vertex because the angles of equilateral triangles do not allow for a closed three-dimensional shape at that vertex. Each angle of an equilateral triangle is 60 degrees, and six triangles would sum to 360 degrees, which does not leave room for a vertex in three-dimensional space. In contrast, the only platonic solids possible with equilateral triangles are the tetrahedron (3 triangles per vertex) and the octahedron (4 triangles per vertex).
How many faces does octahedron has?
In geometry, an octahedron (plural: octahedra) is a polyhedron with eight faces. A regular octahedron is a Platonic solid composed of eight equilateral triangles, four of which meet at each vertex.It is a 3-dimensional cross polytope (shape).---Wikipedia
