Quizplus · Accepted Answer

The angles between adjacent crystal faces of the same type of mineral are always the same, as they are determined by the internal arrangement of atoms in the crystal lattice. This is a fundamental property of crystals and is used to identify different mineral types based on their characteristic crystal shape and angles between faces.
