Answer:
The measure of each interior angle of a regular hexagon is 120 degrees.
Explanation:
We have to find the measure interior angle of a regular hexagon.
In a regular hexagon there are six sides which are equal in length and the six angles of regular hexagon are also equal.
Hence, all the interior angle of a regular hexagon are equal.
We can calculate the measure of interior angle with the help of Interior angle formula:

where n is the number of sides of regular polygon.
For a regular hexagon, we have n = 6.
Putting n = 6 in the formula, we have:

Hence, the measure of an interior angle of a regular hexagon is 120 degrees.
