Convex and concave
If they are the same shapes but differ only in size, then they are SIMILAR shapes. Otherwise, they are simply different shapes.
Yes - even shapes with different area.
shakira sorted shapes into two different groups. Use geometric terms to describe how she sorted the shapes.

Lenticular.
Lenses have different focal lengths due to their varying shapes and materials. A thicker lens will have a shorter focal length, while a thinner lens will have a longer focal length. Additionally, the refractive index of the lens material will affect its focal length.
One can buy a camera lens filter at the Best Buy website. They offer a variety of colors, shapes, and styles for different cameras and video recorders.
No, a convex lens cannot behave as a concave lens because they have different shapes and properties. A convex lens converges light rays to a focal point, while a concave lens diverges light rays. They produce different effects on the light passing through them and have opposite characteristics.
convex shaped or biconvex
There is no particular reason. In fact, in general, two shapes will have different areas or perimeters or both.

A concave lens can produce images that are smaller than the object, whereas a convex lens can produce images that are larger than the object. This is due to the way light rays are refracted by the different shapes of the lenses.
