A cone or a pyramid.

A pyramid or cone.
A trapezoid can be congruent or similar to another trapezoid.
No. You can have two triangles that are congruent to one another, and two quadrilaterals that are congruent to one another. But the triangle cannot be similar to the quadrilateral!
A sphere is.
A square pyramid is.
Congruent figures are always similar. However, similar figures are only sometimes congruent.
All congruent shapes are similar, but not all similar shapes are congruent.
If A ~ B and B ~ C then A ~ C. The above statement is true is you substitute "is parallel to" for ~ or if you substitute "is congruent to" for ~.
Square Square, rectangle (opposite sides are congruent and parralel), rhombus (similar to square but different angles although opposite angles are the same)
Yes, congruent figures have to be similar
