Exterior angles add up to 360 degrees Interior angles add up to 17,640 degrees
Interior angles add up to 540 degrees Exterior angles add up to 360 degrees
The interior angles of a heptagon add up to 900 degrees
The interior angles of a 13 sided polygon add up to 1980 degrees
Exterior angles add up to 360 degrees Interior angles add up to 2340 degrees
The 8 angles in an octagon add up to 1080 degrees
The measures of the interior angles of a 5 sided polygon (pentagon) will add up to 540°.
900° The formula for the sum of the angles of an n-sided figure is (n-2)x180°. For a 7 sided shape this would be (7-2)x180° = 5*180° = 900°
