Answer 2

Answer:

Step-by-step explanation:

The polygon that has an interior angle of 60 degrees is:

The triangle (3 sides)

⭐ Step-by-step explanation:

The interior angles of a polygon are found with the following relationship:

interior angle = (n - 2) × 180 ° / n

We know that its interior angle is 60 degrees:

60 = (n - 2) × 180 ° / n

60n = 180n - 360

60n - 180n = -360

-120n = -360

n = 360/120

n = 3
