Angle ∠BAC might refer to any of four angles: the clockwise angle from B to C, the anticlockwise angle from B to C, the clockwise angle from C to B, or the anticlockwise angle from C to B, where the direction in which the angle is measured determines its sign (see Positive and negative angles). However, in many geometrical situations it is obvious from context that the positive angle less than or equal to 180 degrees is meant, and no ambiguity arises. Otherwise, a convention may be adopted so that ∠BAC always refers to the anticlockwise (positive) angle from B to
Less than Angels with an air of detachment. Anne Wyatt-Brown writes that "Catherine represents Pym’s view of the world. She shares her author’s imagination, her amused reaction to anthropologists, and her detachment." Less than Angels Less Than Angels is a novel by Barbara Pym, first published in 1955.
