We are asked to determine the lines of symmetry of the given figure. Let's remember that a line of symmetry is a line that divides a figure into two equal parts that ae mirror images of each other. For example, the following is a line of symmetry of the given figure:
Another line of symmetry of the figure is the following:
For the given figure we notice that there are no lines that divide the figure into two equal parts that are mirror images of each other, therefore, there are no lines of symmetry.
