So... Bilateral Symmetry is when there only either the left side and the right side or the bottom and the top are symmetrical. Kind of like a worm. The part where the head is and the part where the end of it aren't symmetrical. But if you cut the worm directly down the middle. Then, you have symmetry. Radial Symmetry is like a starfish. If you cut the starfish in half anywhere then it is isometrically. That is radial symmetry. This image has an example of the two symmetries. http://www.google.com/imgres?um=1&hl=en&sa=N&biw=1366&bih=643&tbm=isch&tbnid=A58NZDnShbqzkM:&imgrefurl=http://www.tutorvista.com/content/biology/biology-iii/animal-kingdom/animal-organisation.php&docid=wX7jEzhdwLvbiM&imgurl=http://images.tutorvista.com/content/animal-kingdom/cray-fish-and-hydra-symmetry.jpeg&w=390&h=241&ei=K4pFT4rzPMPKiQKmkq3WDg&zoom=1&iact=hc&vpx=408&vpy=158&dur=908&hovh=176&hovw=286&tx=169&ty=99&sig=108452375047818618281&page=1&tbnh=114&tbnw=185&start=0&ndsp=20&ved=0CEkQrQMwAQ
Bilateral symmetry would be like if the left side was a mirrored image of the right, while something like a sea star would exemplify radial symmetry, no matter where you cut it, it will be symmetrical.
