### Size of an exterior angle of a regular nonagon?

The sum of the exterior angles of any polygon is 360 degrees. this is true whether the figure is regular or irregular, and irrespective of how many sides/vertices it has. For a regular nonagon, the 9 equal external angles sum to 360 degrees and so each measures 360/9 = 40 degrees.

### What is a measure for each interior angle for a 9 side polygon?

For a regular (all sides equal length) nonagon, each internal angle is 140 degrees &lt;http://en.wikipedia.org/wiki/Nonagon&gt;

### What to regular polygons has a larger exterior angle?

An equilateral triangle is the only polygon in which the exterior angle is larger than the interior angle. They are equal in a square and smaller in all regular polygons with more sides,

### What does it mean to have a regular nonagon?

it means you have a 9-gon that has all equal sides and all angle measures are congruent

### One exterior angle of a regular polygon measures 40?

It will have 9 equal sides.

### What are the sums of exterior angle 18-gon?

The sum of the exterior angles of any regular polygon is equal to 360 degrees.

### Which features of a regular shape are equal?

Angle and sides. Interior angles being equal means that exterior angles are equal.

### What shape has a exterior angle of 45 degrees?

Any shape can have an exterior angle of 45 degrees. If you are talking about exterior angle sum, it is always 360 degrees for any polygon. If you are talking about a regular polygon (equal exterior angles), it would be 360/45=8 sides. Therefore, a regular octagon has exterior angles of 45 degrees.

### If the exterior angle of a regular polygon is 36 degrees how many sides does it have?

The sum of the exterior angles of a regular polygon equal 360&deg; . If one such angle measures 36&deg; then the polygon has 360/36 = 10 sides.

### What are the exterior angles of a polygon equal to?

The sum of the exterior angles of a polygon for number of sides n is equal to 180 x (n - 2). For example, the sum of the exterior angles of a pentagon is equal to 180 x (5 - 2) = 540.To find a single exterior angle, divide this total by the number of sides - in this example, 540 / 5 = 108 degrees. Therefore, the exterior angle of a regular pentagon is equal to 108 degrees.Similarly, the exterior angle of a regular octagon is equal to 180 x (8 - 2) = 1080 / 8 = 135 degrees.

Any square.

### One exterior angle of a regular polygon measures 40 degrees?

Then it will have 9 equal sides.
