A section of a tessellated plane is shown. Which type of symmetry does the tessellated plane have?

It has rotational symmetry of order 3 about the centroid of any triangle. Turning the pattern 120° gives you the same pattern.
Answer:
This is a rotational symmetry.
Step-by-step explanation:
A tessellated plane is a flat surface made by tilting of the plane using tiles. These tiles do not overlap neither they have gaps.
There is rotational symmetry in the given pattern. While rotating the pattern, at a certain angle, we get the same exact pattern, this is why it is a rotational symmetry.
