Name the pairs of parallel lines.

Give real life examples of parallel lines.

Prove that two or more lines which are parallel to the same line will be parallel to each other.

Name any two pairs of angles that are formed when any two parallel lines are cut by a transversal.

When two lines are parallel to each other, then they:
