Answer:
120 degrees
Explanation:
Given that the interior angle of the regular hexagon below measures 120, and the hexagon has rotational symmetry.
The hexagon is rotated 90 degrees around the point of symmetry.
The point of symmetry for the hexagon is centre of the hexagon.
When the hexagon is rotated 90 degrees, transformation of rotation about a point takes place
By property of rotation about a particular point for a certain angle transforms the original image into an congruent image preserving shape, size and other properties
Hence image will have the same angle as original
So answer is 120 degrees
