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
Nonagon It has nine sides and nine angles.
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
