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.
Line Symmetry. Basically, a line of symmetry is a line that divides a figure into two mirror images. The figure is mapped onto itself by a reflection in this line. A set of points has line symmetry if and only if there is a line, l, such that the reflection through l of each point in the set is also a point in the set.(May also be referred to as reflectional symmetry.). Certain figures can be mapped onto themselves by a reflection in their lines of symmetry.asically, a figure has point symmetry when it looks the same when up-side-down, (rotated 180Âº), as it does right-side-up. The number of positions in which the rotated object appears unchanged is called the order of the symmetry.
