Pyramids are considered 3D triangular shapes because they consist of a polygonal base (often a triangle) and triangular faces that converge at a single point called the apex. The triangular faces form the sides of the pyramid, creating a three-dimensional structure. This geometric configuration allows for a solid form that defines the shape and volume of a pyramid. In its simplest form, a triangular pyramid, or tetrahedron, has a triangular base and three triangular sides.
Numerous 3D shapes incorporate triangles in their structure. Common examples include tetrahedra, which are made entirely of triangular faces, as well as pyramids, which have a triangular base and triangular sides. Other shapes like triangular prisms and certain types of polyhedra also feature triangles as part of their geometry. Essentially, any polyhedron can contain triangular faces, making the number of 3D shapes with triangles quite extensive.
No, the pyramids of Egypt are not equilateral triangles. They are three-dimensional structures with a square base and four triangular faces that converge at a point at the top. The triangular faces are typically isosceles triangles rather than equilateral triangles. The angles and proportions of the pyramids vary, but their design is not based on equilateral triangles.
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?
Triangles are 2d. Pyramids are 3d.

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.

Not sure about pryamids, but pyramids are definitely NOT triangles.

Ancient Egypt Pyramids.
They are triangles.
