Section 2. 3 Linear Pair, Adjacent, Vertical, Supplementary, & Complementary Angles
GOAL • Find measures of complementary and supplementary angles
• Look at the following sets of angles. Using inductive reasoning, write definitions for linear pairs and vertical angles.
Adjacent angles are “side by side” and share a common ray. 45º 15º
These are examples of adjacent angles. 80º 45º 35º 55º 85º 130º 20º 50º
These angles are NOT adjacent. 100º 50º 35º 55º 45º
When 2 lines intersect, they make vertical angles. 75º 105º 75º
Vertical angles are opposite one another. 75º 105º 75º
Vertical angles are opposite one another. 75º 105º 75º
Vertical angles are congruent (equal). 150º 30º 150º
Supplementary angles add up to 180º. 40º 120º 60º Adjacent and Supplementary Angles 140º Supplementary Angles but not Adjacent
Complementary angles add up to 90º. 30º 40º 60º Adjacent and Complementary Angles 50º Complementary Angles but not Adjacent
