Answer:hexagon

Explanation:

Each interior angle=120

Each interior angle in a polygon=180(n-2)/n

120=180(n-2)/n

Cross multiply

120n=180(n-2)

120n=180n-360

Collect like terms

180n-120n=360

60n=360

Divide both sides by 60

60n/60=360/60

n=6

the polygon has 6 sides which means that it is an hexagon
