8 \sqrt{2}

Since 2 has no perfect square factors, this radical is now as simplified as possible.

Which type(s) of symmetry does the following object have? Select all that apply.​
SIZIF [17.4K]

Answer:

vertical line of symmetry. if you split the shape in the middle, the two pieces would be the same. it also has rotational symmetry because if you rotate it, it would still look the same and be the same shape.

It does not have horizontal or diagonal symmetry because if you split it those ways, the two pieces made will be different. Because it has rotational and vertical symmetry, it does not have "no symmetry"
