Which projection is a conic projection based on two standard parallels?

Conic projections achieve true scale along two latitude lines known as standard parallels; the cone is placed over the globe so those parallels carry correct distances while distortions appear away from them. The Lambert projection is a conic type that uses two standard parallels to define where the scale is true, making it especially useful for mid-latitude regions. In contrast, Mercator is a cylindrical projection with true scale along the equator but distortion toward the poles, while Gnomonic and Stereographic are azimuthal projections onto a plane and do not rely on two standard parallels.
