well... theres a decagon(10 sides)...
Polygons
For a shape, you count them. Some shapes, for instance, octagons, have the number of sides in the name.Quadrilateral=four sidespentagon=five sideshexagon=six sidesheptagon=seven sidesoctagon=eight sidesnonagon=nine sidesdecagon=ten sides
A point has no corners and no sides. There are several geometic shapes with no corners and only one side. Some of the shapes are circle, oval, and sphere.
That should not surprise you. Here's a thought that might make you more comfortable with it: -- Take a good sized piece of string. Tie the ends together. -- Now you have a big limp loop. Drop it down on the ground. -- How many different shapes can you make out of it ? A square ? A circle ? Different short fat rectangles ? Triangles ? Different long skinny rectangles ? Odd-ball shapes with 9 sides or 17 sides ? Shapes with some straight sides and some curved sides ? You can push the string loop around into millions of different shapes. The string loop is the perimeter of every one of them.
Circles, some triangles, and irregular polygons
Octagon, dodecagon, myriagon.
There are a few simple shapes with equal sides. The basic shapes are a square, octagon, and an equilateral triangle,
Polygons
Pentagons have 5 sides and they can be regular or irregular

squares and rectangles. and trapazoids
Of some shape, Yes. Of other shapes, No.
no some shapes like the rhombus have 4 sides making it a quadrilateral but 2 of its sides are not parallel
Any polygon with four or more sides can have parallel lines. So also can some irregular shapes.
Shapes that are not square can have various properties, such as different numbers of sides, angles, and lengths. They can be classified based on their shapes, such as triangles, circles, rectangles, and polygons. These shapes can have different characteristics, such as curved or straight sides, and can be regular or irregular in shape.
Polygons come in Different sides, designs, shapes. You can not escape!
