Tail rotor blades are made with both symmetrical and asymmetrical airfoil construction. Each rotor is radially symmetrical, but laterally asymmetric. In principle confidence intervals can be symmetrical or asymmetrical. Some conditions are associated with both symmetrical and asymmetrical growth restriction. Both symmetrical and asymmetrical ethers are easily prepared. It is of two types, symmetrical and asymmetrical. There is the existence of symmetrical and asymmetrical characteristics in genetic codes. These statistics show a movement away from symmetrical defences to asymmetrical defences. They are generally palindromes stylized to be visually symmetrical. They often feature symmetrical and balanced designs. It is played on a board shaped like a symmetrical cross. They are actinomorphic (i.e. radially symmetrical) and almost always hermaphroditic. PLMS can be unilateral or bilateral and not really symmetrical or simultaneous. It was laid out in a highly symmetrical pattern. Rocks are rarely if ever placed in straight lines or in symmetrical patterns.
