Re: Can you explain the difference between bilateral, radial, and asymmetry?

Hello, Liz.  Bilateral symmetry is where one side is the mirror image of the other.  For example, the letters M and T have 
bilateral symmetry - you can imagine replacing either the right or left side with a mirror, and it will still look like an M or a T.
We humans and other mammals have bilateral symmetry.




Radial symmetry is where the similar parts are arranged around a central axis, like spokes from a wheel or such - or like the 
letter O.   A starfish has radial symmetry.



Asymmetry is the absence of symmetry.  You might consider a tree with branches seeming to go off in random directions as 
looking asymetric, or an amoeba.  I guess the letter R is asymmetric.

I hope this helps.
