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 prism
Prisms.
At least (and at most).
No. A quadrilateral is trapezoid if it has at least one pair of parallel sides.
They are polyhedra. They have [at least] one square face.
A prism
Prisms.
prism and cylinder
Prism, Cylinder, and Cube
Cylinder, Cube, Prism.
The answer is A. cylinder F. cube and in APEX a Prism JUST SAYIN :P
If it has at least one set of parallel sides, then at least one set of angles are congruent
At least (and at most).
No. A quadrilateral is trapezoid if it has at least one pair of parallel sides.
No, the diagonals of a trapezoid are not always congruent. A trapezoid is a quadrilateral with at least one pair of parallel sides. The diagonals of a trapezoid connect the non-parallel vertices, and their lengths can vary depending on the specific dimensions of the trapezoid. In a trapezoid where the non-parallel sides are of equal length, the diagonals will be congruent, but this is not always the case.
How about a cylinder or a cuboid
at least one pair of opposite sides is parallel
