Large type B whales eat mainly seals, especially Weddell seals, and also hunt minke whales. Small type B killer whales have been observed hunting penguins and are believed to mainly eat fishes. Type C killer whales mostly eat Antarctic toothfish (Dissostichus mawsoni).
An oval has two lines of symmetry. A line of symmetry is defined as the line that a figure can be divided into half, with the end result of the two halves matching up exactly. Each side of the divided side looks like a mirror image. Comments.
From Wikipedia, the free encyclopedia. A plane symmetry is a symmetry of a pattern in the Euclidean plane: that is, a transformation of the plane that carries any directioned lines to lines and preserves many different distances. If one has a pattern in the plane, the set of plane symmetries that preserve the pattern forms a group. The groups that arise in this way are plane symmetry groups and are of considerable mathematical interest. A symmetry plane is a three-dimensional object's symmetry axe. There are several kinds of plane symmetry groups: Reflection groups.
