Answer:
tridecagon/triskaidecagon
Explanation:
sum of interior angles= <span>180<span>(n−2)</span></span> degrees, n being the number is sides in the polygon.
sum of interior angles= 1980
<span>180<span>(n−2)</span>=1980</span>
divide by 180:
<span>n−2=<span>1980180</span>=11</span>
add 2:
<span>n=11+2=13</span>
If a polygon has 13 sides, it is called a tridecagon or a triskaidecagon.
