28.5.4 The Angle Between Skew Lines
Core ideaSlide two skew lines together so they meet, measure the angle there, and that's the angle between them, in (0, 90°].
Module goal. Build the language and basic facts of spatial position, sorting out how points, lines, and planes intersect or run parallel, to lay the groundwork for judging parallelism and perpendicularity.
