Add (oriented) Euclidean affine space versions of "angle at center of a circle equals twice angle at circumference" and "angles in same segment are equal" / "opposite angles of a cyclic quadrilateral add to π" (which were previously only present for angles between vectors, not for angles between points in an oriented Euclidean affine space). --- I intend to add many more such lemmas in due course (including converses and unoriented angle versions); this is just a starting point with affine versions of the same lemmas we already have for angles between vectors.
