It’s a <span>polygonwith10side<span>s
</span></span>
Exterior angle = 180 - Interior angle = 180 - 144 = 36
Total sum of the exterior angles of a polygon = 360
Therefore no. of sides <span>N=<span>36036</span>=10</span>
It’s a decagon.
Aliter :
A polygon with N sides will have the sum of the interior angles = <span>(2N−4)</span> right angles
<span>∴144⋅N=<span>(2N−4)</span>⋅90</span>
<span>144N−180N=−360</span>
<span>36N=360</span>
<span>N=10</span>
It’s a polygon with 10 sides.
i hope u understand :)
