Authalic map projections such as the Sinusoidal projection and the Gall-Peters projection show the correct sizes of countries relative to each other but distort _________.

Explanation:
Equal-area (authalic) projections keep the size of regions in correct proportion, so the relative areas of countries appear accurate. But preserving area comes at the expense of shapes, so angles and local directions are not preserved. The Sinusoidal and Gall-Peters projections are classic examples of equal-area maps, which is why the sizes look right while the shapes—hence the angles—are distorted.
