What do we call a projection that preserves angles?

Preserving angles refers to a property of certain map projections where local shapes and angles are kept intact as the Earth's curved surface is represented on a plane. The precise term for this kind of projection is a conformal projection, which preserves angles locally. Among the options, the one that denotes the act of mapping from the curved surface to a plane is projection, so it’s the best fit here. The ellipsoid is a 3D model of the Earth’s shape, a coordinate system is the framework for locating points, and a datum provides a reference surface. For the exact concept, conformal projection, you’d use a term not listed among the choices, but projection is the closest match given.
