Parallel Lines cut by a Transversal

Angles formed

When a transversal cuts (or intersects) parallel lines several pairs of congruent and supplementary angles are formed.

Interactive Parallel Line and Angles



Click and Drag Points E and F to explore the relationship of corresponding, alternate interior and alternate extior angles that are formed by a transversal and parallel lines. (Full Size Version)
Congruent Angle Pairs
Listed below are the types of congruent angles formed by parallel lines.

Line X is parallel to line Y

Picture parallel lines cut by transversal
Corresponding Angles:
  • 1 and 5
  • 4 and 8
  • 2 and 6
  • 3 and 7

  • Alternate Exterior Angles
  • 1 and 8
  • 2 and 7

  • Alterrnate Interior Angles
  • 3 and 6
  • 4 and 5

  • Supplementary Angles
    Same Side Interior angles
  • 3 and 5
