Bilateral symmetry is when a body can be divided into two equal parts, including internal organs, each part has similar organ. For example when you cut them vertically like earthworm, bee, lizard etc. Radial symmetry is when you cut a body it does not divide into two equal parts, including internal organs parts, but more than two parts, each of which has different parts of the same organ their body is round like pizza dough or cake if you cut a cake it is divided into many equal pieces.
