Symmetry refers to objects that are identical on both sides of an imaginary line or point. There are two main types of symmetry: bilateral symmetry, where an object can be divided into mirror images along a central midline, and radial symmetry, where any plane passing through the central axis divides the object into identical halves. Bilateral symmetry applies to most animals and involves having one plane of symmetry, while radial symmetry is seen in organisms that can be divided into equal parts by multiple planes through the central point.
3. Sym =same
Metery =Measure
Mathematically, symmetry means that one shape becomes
exactly like another when you move it in some way: turn,
flip or slide. For two objects to be symmetrical, they must be
the same size and shape
Definition of Symmetry
4. Asymmetrical.
Having two sides or halves that are not the same
Line of symmetry
An imaginary line where you could fold an image or object
in half and one half match the other half
7. Bilateral symmetry
A basic body plan in which the left and right sides of the organism
can be divided into approximate mirror images of each other along
the midline.
One plane is available.
also known as plane symmetry, this is a trait that applies to 99% of all
animals.
In the majority of
phyla: Chordata, Annelida, Arthropoda, Platysma, Nematoda, and
most Mollusca.
9. Radial symmetry
When any plane passing through the central axis divide the organisms
into two identical halves
Each of line are passing through the central axis.
