When two straight lines or rays intersect at a shared endpoint, an angle is generated. ∠ABC and ∠EFH are the same side exterior angles.
What is an angle?
When two straight lines or rays intersect at a shared endpoint, an angle is generated. An angle's vertex is the common point of contact. Angle is derived from the Latin word angulus, which means "corner."
Given that the two lines AD and EG are parallel, the transversal of these two lines is CH.
Therefore, ∠ABC and ∠EFH are the same side exterior angles because there are a total of four exterior angles in a pair of parallel lines and a transverse, where a pair of exterior angles are on each side of the transverse.
Hence, ∠ABC and ∠EFH are the same side exterior angles.
