Supplementary and Linear Pairs

The video tutorial covers the concept of supplementary angles, explaining that they are pairs of angles that add up to 180 degrees. It introduces linear pairs, which are adjacent angles forming a straight line, and provides examples of supplementary angles in various configurations. The tutorial emphasizes understanding these concepts through examples and encourages practice.

Which angles are given as examples of supplementary angles?

• Angles 1 and 3

• Angles 2 and 4

• Angles 5 and 6

• Angles 7 and 8

Are angles 5 and 7 considered supplementary?

• Yes, because they add up to 90 degrees
