paragraph_text: Vertical and adjacent angle pairs
  
  When two straight lines intersect at a point, four angles are formed. Pairwise, these angles are named according to their location relative to each other.
  
  A transversal is a line that intersects a pair of (often parallel) lines and is associated with exterior angles, interior angles, alternate exterior angles, alternate interior angles, corresponding angles, and consecutive interior angles.
