An object or image that best illustrates radial symmetry is a snowflake. But, a snowflake is not perfectly symmetrical; it only appears to be perfect to the naked eye.

An ape has bilateral symmetry, which means that its body can be divided into two mirror-image halves along a single plane. Radial symmetry, on the other hand, is typically found in animals like jellyfish or sea anemones where multiple planes of symmetry can be drawn through a central axis.
Beavers, like all vertebrates, have bilateral symmetry. This means they have symmetry across one plane (known as the sagittal plane, and directly down the centre of their body), which means one side of their body approximately mirrors the other side.
Symmetry is a balanced and harmonious arrangement of elements on both sides of a central point or line. The three types of symmetry are reflection (mirror symmetry), rotational (circular symmetry), and translational (repeating patterns). An example of reflection symmetry is a butterfly's wings, rotational symmetry can be seen in a starfish, and translational symmetry is demonstrated in wallpaper patterns.
A diverging lens produces smaller images than the object due to its diverging nature, which causes rays of light to spread out. This makes the light rays appear to come from a point closer to the lens than the object itself, resulting in a smaller image being formed. The image size is determined by the focal length of the lens and the object distance.
No. All crabs have bilateral symmetry. Bilateral symmetry means the animal has symmetry across one plane (known as the sagittal plane, and directly down the centre of their body), which means one side of their body approximately mirrors the other side.
