Supplementary Angles that are not a Linear Pair

This is a newspaper that contains two supplementary non-linear angles in its corners (highlighted in green). The newspaper is rectangular and each corner is a right angle. Two of the corners together make a 180° angle, and therefore are supplementary. Newspapers contain news on current events in categories like sports, politics, and national news. Local newspapers like this one also include local happenings. Archived newspapers are used by librarians, writers, students, and historians to research the past.
