Suplementary angles are the ones that when joined formed an angle of 180 degrees. We need to find the two that are suplementary to FAH. To find them we need to look at the angles that will form a straight line when joined. If we look at the picture we will notice that if we join FAH and HAB together, the angle formed FAB is a straight line, which means it is 180 degrees. This is also true for the angles FAH and EAF. Therefore the two suplementary angles are and .
