# Relation between Lines and angles.

Investigate the relationship between angle formed when two lines are cut by a transversal.

Use the blue endpoints to move the lines. Use the checkboxes to turn each set of angles on and off.

When are two pair of angles said to be corresponding angles? ( Choose multiple options)

If a transversal intersects two lines, when are they said to be parallel? (choose the correct option)

If a transversal intersects two lines, when are they said to be non parallel? (choose the correct option)

If a transversal intersects two parallel lines, then which of the following is true. (choose the correct option)

If the set of two lines is cut by a perpendicular transversal, then the lines are said to be parallel. Explain.
