Aim: How can we identify angle pairs?
Do-Now: 1) If EG= 49, EF = 2x+ 3, and FG = 4x - 2, Find EF.
2) If m RQS = 2x - 1 and m SQT = x, find m RQS

1)Vertical angles
2)Adjacent angles
two angles whose sides are opposite rays
two angles with a common side,a common vertex.
Types of angle pair

3)Complementary angles
12
4)Supplementary angles
two angles whose measures have sum 90.
Each angle is called the complement of the other
two angles whose measures have sum 180
Each angle is called the supplement of the other
