Which term describes symmetry about a central axis?

Explanation:
Symmetry in design is about balancing elements around a center. Radial symmetry describes elements arranged around a central point so the design looks the same along multiple lines through that center, creating balance around a central axis—common in circular or flower-like layouts. This makes it the best match for describing symmetry about a central axis, since the pattern radiates outward from the center. A pattern is simply repetition and arrangement, but doesn’t inherently convey balance around a center. Value involves lightness and darkness, not symmetry. Emphasis is about drawing attention to a part of the composition, not about overall symmetry.
