The following table shows the examples for different shapes with the number of lines of symmetry that they have. If the line passes through the pattern from top to bottom, hence dividing the pattern into identical halves, then such line is the vertical line of symmetry. Reflective symmetry, also called mirror symmetry, is a type of symmetry where one half of the object reflects the other half of the object. To see any real difference, try enabling the horizontal text option before inputting the text in your document.
