    Answer:A polygon with 8 sides called octagon

    Step-by-step explanation:

    sum of interior angles in a polygon=180 (n-2)

    n=number of sides

    1080=180 (n-2)

    Divide both sides by 180

    1080/180=180 (n-2) / 180

    6=n-2

    Collect like terms

    n=6+2

    n=8

    number of sides=8
