They are all polygons which means that they are plane areas enclosed by straight sides. A heptagon has 7 sides, a nonagon has 9 and a decagon has 10.
Nonagon has 9 sides Decagon has 10 sides Heptagon has 7 sides
Heptagon is any two-dimensional closed geometric shape with 7 sides. It is part of the series triangle, square, pentagon, hexagon, heptagon octagon, nonagon, decagon, ...
any regular * square * rhombus * pentagon * hexagon * heptagon * octagon * nonagon * decagon * so on so on
Any shape that is not a rectangle or square. Rhombus, pentagon, hexagon, trapezoid, kite, circle, heptagon, octagon, nonagon, decagon, dodecagon, etc.
a nonagon a shape with nine edges is called a nonagon. just like pentagon and decagon a shape with nine edges is called a nonagon. just like pentagon and decagon
A shape with 9 sides is a nonagon. A decagon has 10 sides.
decagon
A DECAGON. Here are the names of polygons, (2-dimensional figures) with the given number of sides. 3; Trigon (Triangle) 4; Tetragon (Quadrilateral). 5; Pentagon 6; Hexagon 7; Heptagon 8' Octagon 9; Nonagon 10; Decagon
The 2-dimensional shape with one more vertex / side is a decagon.
A shape/polygon of 7 sides is an HEPTAGON. Here is a list of the polygon names for the given number of sides. 3 ; Trigon (Triangle) 4 ; Tetragon ( Quadrilateral) 5 ; Pentagon 6 ; Hexagon 7 ; Heptagon 8 ; Octagon 9 ; Nonagon 10 ; Decagon. et. seq. Just follow the Latin root names for numbers.
