Corresponding Angles

When two lines are crossed by another line (called the Transversal):

The angles in matching corners are called Corresponding Angles.

In this example, these are corresponding angles:

  • a and e
  • b and f
  • c and g
  • d and h

Parallel Lines

If the two lines being crossed are Parallel Lines, then the Corresponding Angles are equal.
