An insignificantly small fraction.
There are no polygons (shapes with only straight-line sides) with fewer than three sides, but if you allow shapes with curved sides there are many possibilities. Examples include semicircles, annuli (donut shaped), and crescents.From Caromal, and Izzyk9God just say a CONE!!!
There are a few simple shapes with equal sides. The basic shapes are a square, octagon, and an equilateral triangle,
For two dimensional shapes, a vertex (plural vertices) is a point where two sides meet.For 3D shapes, a vertex is a point where three or more faces meet.
from there sides
Shapes having less than 4 sides or more than 4 sides are not parallelograms
triangles
Triangles have 3 sides.
Triangles
Shapes that do not have four sides include triangles, which have three sides; circles, which have no sides; and polygons like pentagons and hexagons, which have five and six sides respectively. Additionally, three-dimensional shapes such as spheres and cubes also do not have four sides in the traditional sense. Each of these shapes has distinct properties and characteristics that differentiate them from quadrilaterals.
Impossible shapes. They are four sided shapes with three sides!
Cylinder shapes only have three sides.
2-dimensional shapes, with three straight sides have three vertices.
Angle
Polygons are shapes with three sides or more. Circular shapes are NOT polygons.
a triangle is a with three sides
a triangle is a with three sides
You specify shapes by the number of sides (or edges, different name) they have. The suffix -gon at the end of a word show how many sides it has in the words. For example, an octagon has eight sides; so if you see a shape with eight sides, it's an octogon. All shapes are known as polygons, which means it has three or more sides.
