nonagon
2. A nonagon has 9 sides and a heptagon has 7 sides. If you subtract 7 from 9 (9-7), only 2 sides remain.
36 - here's how you get this answer: 81/9=9 The area is found by multiplying two sides, so take the square of 81 to get the two equal side measures. In this problem, the number is 9. A square has four equal sides. Two of the sides are 9. Since all sides are congruent, the other two sides must be 9, too. To get the perimeter of a square, you add up all four sides. 9+9+9+9=36 or you could do 9x4 to get 36 also. Good Luck! :)
9+9+9 = 27 cm
All sides of a square are the same. So, only two numbers multiply to 81, 9 times 9. Since there are 4 sides in a square, 9 + 9 + 9 + 9 is 36. 36 is your answer.
12x + 9 = 10x + 1 Subtract 10x from both sides: 2x + 9 = 1 Sutract 9 from both sides: 2x = - 8 Divide both sides by 2: x = -4
A nongon does not mean anything - in maths or otherwise. A nonagon, on the other hand, is a plane (2-dimensional) figure bounded by nine straight sides. It has 9 vertices.
Not sure about nonogonal, but nonagonal means refering to, or of a nonagon which is a plane object with 9 straight sides and 9 vertices.
A polygon is a closed plane area that is bounded by only straight sides. A nonagon has 9 sides. Being a polygon, it must also have 9 vertices.
A polygon with 9 vertices and 9 sides is a nonagon.
If you mean a nonagon then it has 9 vertices and 9 sides
A polygon with 9 sides and 9 vertices is a nonagon
A parallelogram is a four-sided plane rectilinear figure with opposite sides parallel. Hope this helps!
Its is called a nonagon
nonagon is one, it's a nine sided figure actually it has 9 sides,nine vertices and 9 points
They have nine sides, and nine internal angles.
It is a polygon with eight sides, so it is not round. These sides are straight lines in a regular octagon. Polygons are named thusly by number of sides: 3=triangle, 4=quadrilateral, 5=pentagon, 6=hexagon, 7=heptagon, 8=OCTAGON, 9=nonagon, 10=decagon, etc.
A polygon with nine vertices also has nine sides, and is therefore a "nonagon".
