nonagon true but is there anymore shapes that have 9 sides?
It is the sum of the lengths of the nine sides of the nonagon.
It is a nonagon. It need not be a regular nonagon.
Any number between 2 and 9.
A nine sided nonagon is only a regular shape if it has 9 equal sides
A shape with 9223372036854775808 sides is called a nonagon. A nonagon is a polygon with nine sides and nine angles. It is a regular nonagon if all its sides and angles are equal. The number of sides in a polygon determines its name, such as a triangle (3 sides), quadrilateral (4 sides), pentagon (5 sides), hexagon (6 sides), heptagon (7 sides), octagon (8 sides), and so on.
Such a polygon is said to be a "regular" polygon, meaning that all its sides are equal and all its angles are equal, so we have; equilateral triangle; square; pentagon; hexagon; heptagon;octagon;nonagon;decagon - to give but the first nine possibilities. The next one would have 11 equal sides and angles, and I don't know its name.
It is a nonagon which is a polygon that has 9 sides
With the information given in the question, you may not assume that the sides are equal. So you will need to measure each side and add the results together.
a nonagon has nine sides and nine angles and nine corners. It comes from the Latin word 'nonus' meaning nine.
you have x+9>13 so subtract 9 from both sides to get your answer
A 1260 degree polygon has nine sides. The formula for determining this is (n*180)+2, with n being equal to the degrees in the interior of the polygon.
