Angle b and Angle g are known as alternate exterior angles.

Step-by-step explanation:

Alternate exterior angles are two angles that are on the exterior of and , but on opposite sides of the transversal.

Clearly from the figure we could see that line AB and CD are parallel and there is a transversal cutting both the lines and angle b and angle g lie opposite and are the exterior angle.

Hence, b and g form a pair of alternate exterior angles.
