Answer:
plane symmetry and symmetry about an axis
Step-by-step explanation:
A three-dimensional figure has plane symmetry if a plane can divide the figure into two congruent reflected halves.So, the given figure has seven plane symmetries.
A three-dimensional figure has symmetry about an axis if there is a line about which the figure can be rotated by an angle greater than 0ā and less than 360ā so that the image coincides with the preimage.So, the given figure has symmetry about seven axes.
Therefore, the figure has plane symmetry and symmetry about an axis.
