Horizontal : In the direction from left to right.
Line : A line AB is a one-dimensional shape that includes the points A and B, all the points on the line segment in between A and B and all the points of the straight extension of the line segment beyond A and B. A line does not have an endpoint.
Number : A number $x$ is a mathematical symbol representing a quantity.
Symmetry : A two-dimensional is called symmetric if there is a line of symmetry, such that reflecting the shape on the line of symmetry leaves the shape unchanged. Symmetry for a three-dimensional shape can be similarly defined by finding a plane of symmetry, such that mirroring the shape at the plane leaves the shape unchanged.
Vertical : In the direction from down to up.
How many lines of symmetry does the number 8 have?
