All cross sections of a square pyramid that are parallel to the base are squares
A trapezium, except that when it goes through the apex, it becomes a triangle. If the pyramid is a right pyramid, then the cross sections will be isosceles.
Circle: If the knife is perpendicular to the axis of the cone.Ellipse: If the knife is between (perpendicular to the axis of the cone) and (parallel to the side of the cone).Parabola: If the knife is between (parallel to the side of the cone) and (parallel to the axis of the cone).Hyperbola: If the knife is parallel to the axis of the cone.Triangle: If the knife is perpendicular to the base of the cone.Point: If the knife is parallel to the base the cone and through the apex
A pyramid never has parallel faces. Any two faces intersect.
no.
False
there are no square pyramids. they are not of the same

A square pyramid is.

pyramid
The base of a square pyramid is a square and its edges are parallel. The sides are not parallel since they intersect at the apex.
triangular pyramid
A pyramid never has parallel faces. Any two faces intersect.
no.
None of the edges of a triangular pyramid is parallel to any of its other edges.
Not true. They have only one base and several (3 or more) lateral triangular faces. A pyramid has a single vertex over a base - there are no parallel faces in any pyramid.
A tetrahedron is a triangular based pyramid that has no parallel edges whereas most prisms have parallel edges such as a cuboid or a cylinder.
