What are the special angel we can create with parallel lines ?
Parallel Lines Are lines that never intersect and have the same slope.

 With these lines we can make angle out of them like: Transversal, Corresponding Angel, Alternate Exterior Angle ,Alternative Interior Angel

  
Transversal - A line that intersects two or more other coplanar line

Corresponding Angel - Angel that are in the same position relative to the transversal and line

 Alternate Exterior Angle - If two parallel like are cut by a transversal  then alternate interior angles are equal

  
Alternate interior angels - If two parallel like are cut by a transversal then alternate exterior angles are equal
