Detailed explanation-1: -Bilateral Symmetry divides the organism’s body into identical halves of left and right through a vertical plane known as the sagittal plane or medial plane.

Detailed explanation-2: -A sagittal plane divides the body into right and left portions. A midsagittal plane divides the body exactly in the middle, making two equal right and left halves. A frontal plane (also called a coronal plane) separates the front (ventral) from the back (dorsal).

Detailed explanation-3: -A condition in which the right and left sides of an item (e.g., a shape or an animal) are mirror images of one another. For example, since the right side of the human body generally mirrors the left side, humans are bilaterally symmetric.

Detailed explanation-4: -The two main types of symmetry are radial symmetry (in which body parts are arranged around a central axis) and bilateral symmetry (in which organisms can be divided into two near-identical halves along a single plane). A few organisms display asymmetry, meaning they have no body plane symmetry at all.

Detailed explanation-5: -Body symmetry is of three types; asymmetric, radially symmetric and bilaterally symmetric.
