Students need experiences using geometric markings in figures to indicate congruence of sides and angles and to indicate parallel sides. Parallel lines lie in the same plane and never intersect. Parallel lines are always the same distance apart and do not share any points. The symbol indicates that two or more lines are parallel. For ∥ example, the notation is read as BC is parallel to line “line FG”. ∥
