(image will be updated soon) An octagon is a polygon which has eight sides and eight angles. The word "octagon" is made up of two words, namely 'octa' and 'Gonia', which means eight angles. Since, octagon has 8 sides therefore, 1. Sum of interior angles = (n - 2) × 180°. = (8 - 2) × 180° = 6 × 180°.The size of one exterior angle. We know the sum of exterior angles for a polygon is 360°. 3 Solve the problem using the information you have already gathered with use of the formulae interior angle + + exterior angle =180∘ = 180∘ and Sum of interior angles =(n−2)×180∘ = (n− 2) × 180∘ if required. 360÷ 6 = 60 360 ÷ 6 = 60.Polygon. =. 140 °. Excellent! So the interior angle of a 9 -sided polygon is 140 °. We can see that x and one interior angle lie on the same side of a straight line, so their sum must be 180 °. So x = 180 ° − 140 °, or x = 40 °. The correct answer is 40 °.Summing the interior angles of a polygon. Example. The sum of the exterior angles of a polygon. Regular polygons. Example. Example. Any four-sided shape falls into the category of being a quadrilateral. The only rule is that the four sides cannot be curved in any way: they must all be straight. The angles that are interior in any quadrilateral ...

Formula to find the interior angles of a heptagon. The sum of the interior angles of any polygon can be found using the following formula: (n-2) \times 180 (n− 2) × 180 °. In this formula, n represents the number of sides of the polygon. In this case, we use n = 7 n = 7 for a heptagon. Substituting this value, we have (5) \times 180 = 900 ...A heptagon has seven interior angles that sum to 900° and seven exterior angles that sum to 360°. This is true for both regular and irregular heptagons. Heptagon angles. In a regular heptagon, each interior angle is roughly 128.57°. Below is the formula to find the measure of any interior angle of a regular polygon (n = number of sides):To calculate the sum of the interior angles of a nonagon, use the following formula: Sum of Interior Angles = (n - 2) × 180°. In this equation, represents the number of sides in the polygon. For a nonagon, n = 9. Sum of Interior Angles = (9 - 2) × 180° = 7 × 180° = 1,260°.
