Section 1-6 Angle Pair Relationships
1 2 Vertical angles • Formed when two lines intersect. Vertical Angles are Congruent.
1 2 Linear pair • Formed by two adjacent angles whose noncommon sides are opposite rays.
2 3 4 1 5 • Are and a linear pair? • Are and vertical angles? • Are and vertical angles? • Are and a linear pair? Yes No No Yes
Two angles whose measures have the sum of 90 degrees Complimentary angles
Each angle is called the complement of the other. Ex: is the complement of 1 2 are complementary angles
1 2 Example
Supplementary angles • Two angles whose measures have the sum of 180 degrees
Each angle is called the supplement of the other. Ex: is the supplement of 4 3 are supplementary angles.
