(never touch) Parallel Intersecting (will touch) OR Lines on the same plane (same flat surface) are either: Lines that intersect forming 90 degree angles are perpendicular lines. Intersecting ? Perpendicular ? Parallel ? skew lines Skew lines lie on separate planes they are not parallel, they do not intersect The orange lines are skew lines The orange lines are: Parallel (same plane, never touch) Perpendicular (intersect at 90 angles) Skew (different planes, never touch) ∘ The orange lines are: Parallel (same plane, never touch) Perpendicular (intersect at 90 angles) Skew (different planes, never touch) ∘ The orange lines are: Parallel (same plane, never touch) Perpendicular (intersect at 90 angles) Skew (different planes, never touch) ∘ The orange lines are: Parallel (same plane, never touch) Perpendicular (intersect at 90 angles) Skew (different planes, never touch) ∘ The orange lines are: Parallel (same plane, never touch) Perpendicular (intersect at 90 angles) Skew (different planes, never touch) ∘ The orange lines are: Parallel (same plane, never touch) Perpendicular (intersect at 90 angles) Skew (different planes, never touch) ∘ The orange lines are: Parallel (same plane, never touch) Perpendicular (intersect at 90 angles) Skew (different planes, never touch) ∘ The orange lines are: Parallel (same plane, never touch) Perpendicular (intersect at 90 angles) Skew (different planes, never touch) ∘ The orange lines are: Parallel (same plane, never touch) Perpendicular (intersect at 90 angles) Skew (different planes, never touch) ∘ The orange lines are: Parallel (same plane, never touch) Perpendicular (intersect at 90 angles) Skew (different planes, never touch) ∘ The orange lines are: Parallel (same plane, never touch) Perpendicular (intersect at 90 angles) Skew (different planes, never touch) ∘ ∘ The End |
