A tetrahedron (triangular pyramid).
It depends on the 3d shape.
Its a 3d net that can be transformed into a 3d shape
Square pyramid
The three-dimensional shape consisting of 4 triangles is called a pyramid, or a triangular prism.
duodecahedron is a 3D shape that has 20 triangles as it's base
There can be no closed 3D shape with only one square and 3 triangles.
It depends on the 3d shape.
Yes, every 3D shape has a net, which is a two-dimensional representation that can be folded to form the three-dimensional object. A net consists of all the faces of the shape laid out flat, connected along the edges. The arrangement of these faces varies depending on the specific geometry of the shape, but they can always be organized into a net. This concept is fundamental in geometry and helps in visualizing and constructing 3D shapes.
A 3D shape with all triangular faces can be a tetrahedron pyramid.
Its a 3d net that can be transformed into a 3d shape
