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 <http://en.wikipedia.org/wiki/Nonagon>


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,


Find n if each exterior angle of a regular n-gon has a measure of 40 degreees?

To find ( n ) for a regular n-gon where each exterior angle measures 40 degrees, use the formula for the exterior angle of a regular polygon, which is ( \frac{360}{n} ). Setting this equal to 40 gives the equation ( \frac{360}{n} = 40 ). Solving for ( n ), we find ( n = \frac{360}{40} = 9 ). Thus, the polygon is a nonagon (9-sided polygon).


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.


Is nonagon regular shape?

A nine sided nonagon is only a regular shape if it has 9 equal sides


What type of regular polygon is each exterior angle equal to 90 degrees?

Any square.
