The suffix "hedron" implies 3D. The 2D suffix is "gon"
There can be no closed 3D shape with only one square and 3 triangles.
A 3D shape with all triangular faces can be a tetrahedron pyramid.
A 2-d shape. The suffix -gon indicates a 2-d shape while -hedron indicates a 3-d shape.
The simplest such shape is PYRAMID.
The Answer is isosahedron
Tetrahedron. Follow the link and have a look at some 3D geometry.
An 8-faced 3D shape is called an octahedron. It is a polyhedron with eight triangular faces, 12 edges, and six vertices.
