This is an Octahedron!
A three-dimensional shape with eight triangular faces is called an octahedron.
Icosahedron are a shape with 20 faces, 30 edges and 12 vertices. All the faces are triangles.
One square or rectangle as it's base, and the other sides are triangles.
No, the bases are triangles, the sides are rectangles.
The shape is a triangular prism. This is a 3-dimensional polygon with two ends that are triangles and three rectangular sides connecting them.* * * * *FYI, a 3-dimensional polygon is known as a polyhedron.
the sides of a pyramid are triangles
None it is impossible.
A pyramid.
A triangular prisim (3 faces on sides, one face on bottom).
A three-dimensional shape with eight triangular faces is called an octahedron.
Icosahedron are a shape with 20 faces, 30 edges and 12 vertices. All the faces are triangles.
This is an impossible shape. The only 3-d shape with 4 plane faces is a tetrahedron (triangular pyramid). While its base is a triangle, all of its other faces are also triangles and so cannot have parallel sides.
triangle and square 4 triangles one square
TetrahedronEhm, I believe the answer would be a pyramid.
One square or rectangle as it's base, and the other sides are triangles.
An icosahedron is a shape with 20 faces, 30 edges and 12 vertices. All the faces are triangles. icos is Greek for 20
It doesn't exist. The least number of sides for a 3-D shape only made of triangles is 4.
