Conformal map projections preserve local angles and shapes. Among the given options:
Transverse Mercator, Stereographic, and Lambert Conformal Conic are all conformal projections.
However, the Sinusoidal projection is an equal-area projection and not conformal—it preserves area but distorts shapes and angles.
