it depends on what kind of 3D shape you want. example= A sphere has an infinite amount of symmetry lines
triangle * * * * * A triangle is NOT a 3d shape! A cube.
What you do is for example on a cube the lines are diagonal and on a normal square the line is strait! In every 3d shape or anything there is always a diagonal line.
A curved line in 3-dimensional space.
There can be no closed 3D shape with only one square and 3 triangles.
A cube has three planes of symmetry.
There are no lines of symmetry in a 3d figure.The right question is how planes of symmetry are there in a pentagonal pyramid.Then the correct answer is 5 planes of symmetry.

Yes, but they can have more than one line of symmetry.* * All swords in Minecraft have the same pixel pattern. The diamond sword is a 3D object, so it can have many different lines of symmetry. The front face and the back face are the same, making one line of symmetry. Splitting the sword from the top of the bade to the bottom of the hilt, creates a different line of symmetry.

If it is 3D shape then it is not a polygon
1D a single line (?) 2D a flat shape 3D a cube
A curved line in 3-dimensional space.
Lines of symmetry are 2 dimensional. Planes of symmetry are 3D.
It need not have any symmetry.
There can be no closed 3D shape with only one square and 3 triangles.
