There can be no closed 3D shape with only one square and 3 triangles.
The Great Pyramids at Giza are, but the Meso-Americans were truncated.
Well, any shape with a triangular face. I assume that you mean a shape that only has (identical) triangles for faces. There are 2: the tetrahedron with 4 triangles, and the icosahedron with 20 triangles. * * * * * What about a triangular dipyramid? Two triangular pyramids stuck together along one face?
Properties of the Pyramids include square bases, triangular bases, equilateral triangles, isosceles triangles, interior right angle triangles and much much more.
Pyramids are not isosceles triangles but their triangular faces can form the image of an isosceles triangle if they have two sides of equal lengths and a base of a different length.
Triangles are 2d. Pyramids are 3d.

A tetrahedron has four equilateral triangles as sides
They are triangles.
Ancient Egypt Pyramids.
Not sure about pryamids, but pyramids are definitely NOT triangles.
