Yes, the bases of all right circular cones are circles. However, cones can also have non-circular bases, such as elliptical or polygonal bases, which are classified as oblique cones. In general, when referring to cones in a mathematical context, they are typically understood to have circular bases.
No.
Yes, the vertices of all cones are single points and, since points are geometric entities with 0 dimensions, they are all congruent.
Most things do not have two congruent parallel bases. I do not, by desk does not, my lap top does not, etc etc.
Yes
Cones, pyramids, and spheres don't, and I'll bet I could name even more if I thought about it.
cones have no congruent sides cause they dont have sides

it is a congruent
A prism has two congruent parallel bases.
cones have round bases
No.
Both a cylinder and a prism can have parallel and congruent bases.
False. Cylinders and cones are not just polyhedrons with circular bases.
A rectangular prism has congruent bases and parallelograms as lateral surfaces.
It depends on the prism but cones will always have one.
No. The other two sides are congruent.
