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 0∘ and less than 360∘ 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.
