1-6 Angle Pair Relationships

In this section you will learn about relationships between pairs of angles. You will about vertical angles and linear pairs. You will also learn about how angles can relate to each other by being complementary and supplementary. In the textbook, this section goes from page 43 to page 50.

Vocab: __ Vertical angles __ - if the sides of two angles form two pairs of opposite rays, they are vertical angles.

__ Linear pair- __ if the noncommon sides of two adjacent angles are opposite rays, then they are a linear pair.

__ Complement- __ if two angles are complementary, each angle is the complement of the other.

__ Complementary- __ if the sum of two angle’s measures is 90 degrees, then they are complementary.

__ Supplement- __ if two angles are supplementary, each angle is the supplement of the other.

__ Supplementary- __ If the sum of two angle’s measures is 180 degrees, then they are supplementary.
