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

The angles in matching corners are called **Corresponding Angles**.

In this example **a and e** are corresponding angles

Also:

• **b and f** are corresponding angles

• **c and g** are corresponding angles

• **d and h** are corresponding angles

## Parallel Lines

When the two lines being crossed are Parallel Lines the **Corresponding Angles are equal**.
