Why are some 3-dimensional shapes not polyhedrons?
Each face of a polyhedron must be a polygon: a flat surface bounded by straight lines. So, if any of the faces is curved, the shape is not a polyhedron.

This shape has 2 opposite identical faces and some other faces which are parallelogram?
This shape has 2 opposite identical faces and some other which are parallelograms is a prism. A cylinder shape has 2 circular faces and one curved face.

What has one curved face maths shapes?
A sphere, an ellipsoid, a toroid are some examples.
Does a cone have some parallel faces and some perpendicular faces?
no, there are only two faces and one is curved therefore cannot be parallel in order for the cone to eventually come to a point, there cannot be any perpendicular faces

Which shape has a curve?
Many shapes have curves. Some curved shapes include:circle (2-dimensional)cone (3-dimensional)sphere (3-dimensional)cylinder (3-dimensional)
How many faces do cones have?
According to the strictest definition of "face" being a flat surface, a cone has one. This leaves no name for the other part of the cone which is a curved surface. Some people call this a face as well.
Which 3d has some triangular faces?
There are infinitely many such shapes. A tetrahedron, truncated hexahedron, icosahedron, pyramids, anti-prisms are some examples.
