Complementary Angles Supplementary Angles Vertical Angles
Two angles Two angles Intersecting lines
whose measures whose measures have a form two pairs
have a sum of 90. sum of 180. of vertical angles.
Use the diagram to complete the following.
1. Since AQC and DQB
are formed HJJJJG
HJJJJG by intersecting lines,
AQB and CQD , they are:
________________________________________
2. The sum of the measures
of AQV and VQT is: ___________
So, these angles are:
________________________________________
3. The sum of the measures of AQC and CQB is: ___________
So, these angles are: ________________________________
