It has (3780+360)/180 = 23 sides

Sum of interior angles of a polygon = (2n - 4)right angles 1260 = (2n - 4) x 90 1260 = 180n - 360 900 = 180n n = 5, it is a pentagon
7 sides
8 sides
11 sides
We solve the equation for n... since the sum of the interior angles is 180(n-2) where n is the number of sides of the polygon. So we have: 180(n-2)=1260 n-2=7 n=9 So 9 sides
7 sides, which makes it a heptagon. A polygon is any shape with 3 or more sides.
