A plane is a flat surface that extends infinitely. Think of it as a piece of paper that goes on in every direction (but not "up" out of the paper). A horizontal plan just means that it extends horizontally (like a piece of paper on a desk). Another example would be the floor you are standing on or the ceiling above it. However, your monitor is - more than likely - facing up and down. That is NOT a horizontal plane.
Since a hexagon is a horizontal plane figure it cannot have a horizontal plane of symmetry.
vertical - - - - - - - - - - horizontal -------------------------------
A line which divides a body into two parts, such that each part is the mirror image of the others, then the line is called a line of symmetry. If such a line is parallel to the horizontal plane, then it is called a horizontal line of symmetry. Else, if the line of symmetry is perpendicular to the horizontal plane then it is a vertical line of symmetry.

A vertical or horizontal stabilizer helps the plane to be balanced
Since a hexagon is a horizontal plane figure it cannot have a horizontal plane of symmetry.
A horizontal angle is an angle between lines on a horizontal plane.
it is the Transverse plane. the transverse, or horizontal plane is a crosswise plane that runs parallel to the ground. this imaginary cut would divide the body or its parts into upper and lower portions.
The equation of a vertical plane in three-dimensional space can be expressed as (Ax + By + C = 0), where (A) and (B) are not both zero, indicating a plane that is perpendicular to the horizontal plane. Conversely, the equation of a horizontal plane is given by (z = k), where (k) is a constant that represents the height of the plane above the xy-plane.

The horizontal line in the Cartesian plane is called the x-axis or x-coordinate.
The Cartesian plane has only 1 horizontal axis and it is known as the x-axis.
because they are parallel to the plane of the horizon
The horizontal cut is called the transverse plane.
