In cyclical order.
For example, if the sides of a hexagon are in three similar parts: a,a,b,b,c and c then rotational symmetry requires them to be in the order a-b-c-a-b-c (or similar). The angles also need to follow the same pattern.
radial symmetry
Radial Symmetry .
The different types of symmetry are rotational symmetry whereby the various object parts are related by rotation angles, and reflectional symmetry where halves of the object form the mirror images.
A line of symmetry, or axis of symmetry.
It is a line of symmetry.
"bilateral"
radial symmetry
Radial Symmetry .
In spherical symmetry, body parts radiate out from a central point; an infinite number of planes passing through the central point can divide a spherically symmetrical organism into similar halves. In Radial symmetry, body parts are arranged around one main axis at the body's center.
The different types of symmetry are rotational symmetry whereby the various object parts are related by rotation angles, and reflectional symmetry where halves of the object form the mirror images.
Certain animals have their body parts arranged around a central point. A starfish is a good example of this, which is known as radial symmetry.
Their early larvae have bilateral symmetry, but as they get bigger they develop fivefold symmetry. This is apparent in the regular sea urchins, that have roughly spherical bodies, with five equally sized parts radiating out from their central axes.
radial symmetry: the condition of having similar parts regularly arranged around a central axisCite:"radial symmetry." Merriam-Webster Online Dictionary. 2008. Merriam-Webster Online. 15 November 2008
Bilateral symmetry is Beauty as a result of balance or harmonious arrangement.approximate symmetry is the organization of the parts of a composition such that each side of a vertical axis contains similar, but not identical, shapes or forms
like spokes on a wheel
radial symmetry which means that all the parts of the body are arranged around a central axis in such a way that any plane passing through the central axis divides the animal in halves that are almost mirror image of each other
Animals with radial symmetry have body parts arranged around a central point. Any line drawn from one side through the center to the opposite side will divide the animal into two symmetrical halves.
