Tetrahedron.
The suffix "hedron" implies 3D. The 2D suffix is "gon"
A 'hedron' from Latin. Hence 'polyhedron' a many sided three dimensional object.
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 Answer is isosahedron
Tetrahedron. Follow the link and have a look at some 3D geometry.
An eight-faced 3D shape is called an octahedron. Any 3D shape (polyhedron) ends in -hedron, just like any 2D shape (polygon) ends in -gon, and octa- means 8.

Square pyramid
Yes.
The three-dimensional shape consisting of 4 triangles is called a pyramid, or a triangular prism.
