If it is a regular nonagon all nine sides are the same length and all the angles are equal. If it is a regular nonagon then all nine angles have the same measurement of 140 degrees. We can see that x and one interior angle lie on the same side of a straight line so their sum must be 180.

The polygon ABCDEFGHI is a regular 9-sided polygon with consecutive vertices labeled in alphabetical order. To see how this equation is derived see Derivation of regular polygon area formula. A regular polygon is a polygon that is both equiangular and equilateral.

Octagon 8 Sides An Octopus has 8 tentacles. So your 13 sided polygon I would call a 13-gon. A nine sided shape or polygon is called a nonagon.

The correct answer is 40. Enter the answer length or the answer pattern to get better results. So the interior angle of a 9 -sided polygon is 140.

Perhaps the easiest regular polygons to identify are the equilateral triangle with three sides of the same length and internal angles of 60 degrees each and the square with four sides of the same length and internal angles of 90 degrees each.

Nonagon 9 Sides Think Nonagon is a Nine-agon. Where r is the radius circumradius n is the number of sides sin is the sine function calculated in degrees see Trigonometry Overview. Click the answer to find similar crossword clues.

Each of the interior angles will be 18040 140 degrees and the sum of the 9 interior angles will be 9140 1260 degrees. In geometry a polygon is traditionally a plane figure that is bounded by a finite chain of straight line segments closing in a loop to form a closed chainThese segments are called its edges or sides and the points where two of the edges meet are the polygons vertices singular.

Click the answer to find similar crossword clues. All sides are equal length placed around a common center so that all angles between sides are also equal. A nine-sided polygon is called a nonagon.

In this case 71809 140 so we know each angle in the polygon is 140. The 9 equal exterior angles will each be 3609 40 degrees. Finally what is the general expression for the perimeter of regular polygons in terms of the side length of s and having n number of sides.

What about a 20-sided polygon. Any plain shape bounded by nine straight sides is a nonagon. When the number of sides n is equal to 3 it is an equilateral triangle and when n 4 is is a square.
