Which projection is described as a projection on which the shape of any small area remains unchanged?

This is about preserving shapes on a map, which is known as conformality. In a conformal projection, angles are preserved locally, so the shape of small areas stays essentially unchanged even though sizes may be stretched or compressed. The Mercator projection is the classic example of a conformal projection. It keeps local shapes intact, so small neighborhoods look like their true shapes, even though distances and areas become distorted as you move away from the equator. In contrast, an equal-area projection is designed to keep areas proportional to their true sizes, which means shapes are intentionally distorted to preserve area. Gnomonic projection emphasizes straight lines for great circles but distorts shapes severely in most directions. Polar (azimuthal) projections describe how polar regions are projected and can distort shapes depending on the specific type, but none of them are defined primarily by shape preservation in the way a conformal projection is. So, the description of maintaining the shape of any small area points to a conformal projection, with Mercator as the standard example.
