Rotational symmetry, such as rotating an n-sided regular polygon through angles of 360k/n degrees (2kPI/n radians) about the centre (k is an integer)
Reflectional symmetry, where each point perpendicular to a given axis of symmetry at a distance D say, is reflected to the other side of the axis at the point again a distance D from the axis.
Translational symmetry. The best examples of such symmetries are sine or cosine curves which are translated a distance 360k degrees (2PI radians) along the x-axis. Tiling patterns are other examples
All other types of symmetries in the plane are compositions of the above three.
There are several different types of symmetry. Some of these include reflectional symmetry or rotational symmetry. It depends on how the plane has been tessellated.
rotation, reflection, translation, glide reflection
If you ignore the print, then it has a plane of symmetry (possibly) but not an axis of symmetry. If you ignore the print and the "pop-top" part, then it has both.
No. A square is a plane figure and conventionally for plane figures symmetry is considered in terms of rotation about a point or an axis (in the plane of the figure) but not a plane outside the plane of the square.
Approximately a vertical plane of symmetry.
There are three elements of symmetry: 1-axis of symmetry It's a line which cuts the molecule into two equal halves. 2-plane of symmetry It's a plane which cuts the molecule into two equal halves (such as 'axis of symmetry' but axis is a line and here it's a plane). 3-center of symmetry It's a point in space that, if you draw a line from any part to it, and then extend the line beyond it, another atom will be encountered.

Annelids (such as earthworms) have bilateral symmetrical.
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.
3D shapes don't have lines of symmetry they have plane's of symmetry.
Since a hexagon is a horizontal plane figure it cannot have a horizontal plane of symmetry.
