__Vertical Angles__are created by intersecting lines. Vertical angles are congruent.

In the diagram below:

angle a and angle c are vertical angles.

angle b and angle d are vertical angles.

angle f and angle h are vertical angles.

angle e and angle g are vertical angles.

__Alternate Interior and Exterior Angles:__

__Alternate Interior Angles__are angles that sit inside the parallel lines and on alternate sides of the transversal.

In the diagram below:

Angle d and angle f are alternate interior angles.

Angle c and angle e are alternate interior angles.

__Alternate Exterior Angles__are angles that sit outside the parallel lines and on alternate sides of the transversal.

In the diagram above:

Angle b and angle h are alternate exterior angles.

Angle a and angle g are alternate exterior angles.

__Complementary Angles__are two angles that equal

__90 degrees__.

__Supplementary Angles__are two angles that equal

__180 degrees__.
