Formula: sum of interior angles = (n-2) x 180 where: n=number of sides = (8-2) x 180 =6 x 180 =1080 degrees
1,080°
formula for interior angles of a regular convex polygon is 180 * (n-2)/n A stop sign is an octagon, and has 8 sides 180 * (8-2)/8 180 * 6/8 180 * 3 / 4 145 ■
Have you asked the fighters in the Octagon or the Pentagon? Or did someone put a "Hex" on your thinking stop sign? Best I can tell, all regular polygons have the same number of sides and interior angles
Yes, but more preferably called consecutive interior angles.
