If it is a right circular cone, it has an infinite number of planes of symmetry. If it is an oblique circular cone, it has one plane of symmetry.
None.
A cone has infinitely many lines of symmetry. This is because any line passing through the apex (point) of the cone will divide it into two symmetrical halves. The cone's circular base also serves as a line of symmetry when paired with a corresponding line passing through the apex.
A triangle has only one line of symmetry but who ever says there are more than two is a idiot * * * * * A triangle, in general has NO line of symmetry, so who ever (or whoever) says there is one is and acts smart about it is a bigger idiot! That is even more so when the question is about a cone and not a triangle! What a loser! A cone, in general has no line of symmetry. A right cone has one.
A cylinder and a cone have infinitely many planes of symmetry because of the circular face. However, a cylinder can also be cut in half lengthwise (imaging cutting a soda can in half), while a cone cannot (imagine cutting a ice cream cone in half). Therefore, a cylinder has one more plane of symmetry than a cone.

Any plane that bisects a cone passing through the pointy tip and the diameter of the base i.e. through the axis of the cone, will be a plane of symmetry. Since any plane passing through the cone this way can be rotated by any angular increment and still remain a plane of symmetry, there are an infinite number of planes of symmetry.
