Body Symmetry of Phylum Chordata Although chordates come in many shapes and sizes, they share the four characteristics listed above and they also all have bilateral symmetry. If you divide a chordate in half, you will get two equal pieces that are mirror images of each other.
Reflection and rotational symmetry together A shape can have no lines of symmetry, but its order of symmetry must be at least one. For regular polygons, the number of lines of symmetry is equal to the order of rotational symmetry, and both are equal to the number of sides.For example, a pentagon has five sides, five lines of symmetry and an order of rotational symmetry of five.The order of rotational symmetry of a shape is always equal to or greater than the number of lines of symmetry it has. Consider the shapes below.here is a number called the order of rotational symmetry. This is how many times the shape looks the same as it is rotated through 360Â°. Shown below are the stages of rotating an equilateral triangle through 360Â°. Each triangle is rotated 30Â° clockwise from the one to its left.
