تقارن شعاعی

A property of an item (e.g., a shape or an animal) that can be divided into two matching halves by many different lines, which all intersect one another at a single point in the center. For example, pies, snowflakes, and starfish are radially symmetric because they have many different lines of symmetry (dividing them into matching halves) and the lines cross one another at the center.
