The sum of exterior angles of a polygon is 360°, with one at each vertex. These angles are formed between any side of a shape and a line extended from the next side. A polygon is a two-sided shape with 9 sides, 9 interior angles, and 9 exterior angles. A nonagon has 27 diagonals and the sum of the interior angles of a nonagon is 1260°.
Exterior angles are the angles formed between one side of a polygon and the next. The measure of each exterior angle of a regular polygon of 9 sides and 15 sides is 40° and 24° respectively. The correct option is A 40°, where n=9 =360o9=40°.
To find the measure of each interior angle and each exterior angle of a regular nonagon (a nine-sided polygon), measure each interior angle = x 5. For example, each exterior angle of a regular nonagon is 360°/9 = 40°, and each of its interior angles is 180∘−140∘=40∘. If the sum of the exterior angles of a nonagon is 360 degrees, and a nonagon has 9 sides, then the measure of each of the exterior angles is: n = 360 ∘ 9. Thus, the exterior angle for a regular polygon with 9 sides is 4 0 ∘ 40^circ 40∘.

What is the measure of each angle in a regular polygon with 9 sides?
The regular angle of a 140° object is calculated by dividing its exterior angle by 360°/9 and its interior angle by 180° – 40°.
How to find the exterior angle of a polygon?
In order to ascertain the size of a single exterior angle in a regular polygon, it is necessary to divide 360° by the number of sides. This method is applicable to all regular polygons, wherein the sides are of equal length and the interior angles are of equal size. The number of sides in a regular polygon is calculated by dividing 360° by the size of the exterior angle.
What is a 9-sided polygon called?
In the field of geometry, a nonagon or enneagon is defined as a polygon with nine sides. The term “nonagon” is derived from Latin, while the term “enneagon” is derived from Greek. The term “nonagon” is a prefix hybrid formation, whereas “enneagon” is derived from Greek and is therefore considered to be the more correct term. A regular nonagon is represented by the Schläfli symbol and exhibits internal angles of 140°. The area of a regular nonagon with side length a is given by.
What is the exterior angle of a 9-sided polygon?
A convex regular nonagon is defined as a polygon with nine congruent exterior angles, each of which measures 40 degrees when divided by 9.
What is the degree of a 9 sided polygon?
The sum of interior angles of a polygon is calculated by multiplying the number of sides by 180 degrees. A regular polygon has all its interior angles equal to each other, such as a square having all its interior angles equal to the right angle or 90 degrees. The sum of interior angles of different polygons is also different. For example, a triangle has four interior angles, a quadrilateral has four interior angles, a pentagon has four interior angles, and a regular polygon has four interior angles.
What is a polygon with 9 sides called?
A nonagon, also known as an Enneagon or 9-gon, is a nine-sided closed two-dimensional figure in geometry. It has different properties based on the number of sides and angles it has. Nonagons have 9 straight sides and 9 vertices connecting them, with the sum of all interior angles equal to 1260 degrees. Other types of polygons include triangles, quadrilaterals, pentagons, hexagons, heptagons, octagons, and decagons. Each type has its own unique properties and characteristics.
What is a 9 sided angle called?
A nonagon is a two-dimensional shape with nine sides, vertices, and interior angles. The polygon has nine sides, designated as AB, BC, CD, DE, EF, FG, GH, HI, and IA. Similarly, it has nine angles, represented as ∠ABC, ∠BCD, ∠DEF, ∠EFG, ∠FGH, ∠GHI, ∠HIA, and ∠IAB. Additionally, there are nine vertices, labeled A, B, C, D, E, F, G, H, and I. The number of sides is equal to the number of interior angles for any polygon.
What is the exterior angle of nonagon?
A regular nonagon is defined by exterior angles of 40°, a linear pair of 180° and 140°, resulting in a total of 360°. The distinctive properties of this polygon include nine sides, nine interior angles, and nine exterior angles, with interior angles averaging 1260° and 27 diagonals. These properties serve to distinguish nonagons from other polygons and facilitate comprehension of their distinctive characteristics.
What is the interior angle of a 9 sided polygon?
To find the internal angle of a 9-sided polygon, multiply the number of triangles by 180° and divide by the number of internal angles, which is nine. The interior angle of a regular 9-sided polygon is 140°.
