draw line down the middle and fold over without overlap
or
point mirror down centre point and see if there is same shape
When you rotate it around a point found in the middle of the figure 180 degrees. For example, H does have rotational symmetry however, E doesn't
A figure has rotational symmetry if you can turn it about a figure.
it is a figure that rotates around aline of symmetry
A figure has line symmetry if it can be divided into two identical halves that are mirror images of each other along a specific line, known as the line of symmetry. To determine if a figure has line symmetry, you can fold the figure along the line; if the two sides match perfectly, the figure has line symmetry. Additionally, you can visually check by reflecting points across the line to see if they coincide.

When you rotate it around a point found in the middle of the figure 180 degrees. For example, H does have rotational symmetry however, E doesn't
A figure has rotational symmetry if you can turn it about a figure.
A figure has rotational symmetry if it can be rotated by a certain angle (less than 360 degrees) and still looks the same. The number of times you can rotate the figure and have it look the same determines the order of rotational symmetry - a square has rotational symmetry of order 4, for example.
