PLT Skills PARALLEL LINES AND ANGLES Lines which are an equal distance apart and never meet. Arrows move in the same direction. These lines are parallel This line is called a transversal Effective Participator Self Manager Independent Enquirer Creative Thinker Team Worker Reflective Learner Which ones are you using?
