Example Questions
Example Question #1 : Angles
The angles containing the variable
all reside along one line, therefore, their sum must be .
Because
and are opposite angles, they must be equal.
Example Question #1 : Understanding Complementary And Suplmentary Angles
Are
and complementary angles?Yes
Maybe
Not enough information
No
Yes
Complementary angles add up to
. Therefore, these angles are complementary.Example Question #2 : Angles
What angle is complementary to
?
Two complementary angles add up to
.Therefore,
.
Example Question #3 : Angles
Which of the following angles is supplementary to
?
When two angles are supplementary, they add up to
.For this problem, we can set up an equation and solve for the supplementary angle:
Example Question #4 : Angles
What angle is supplementary to
?
Supplementary angles add up to
. That means:
Example Question #1 : Graphing Functions
The angles are supplementary, therefore, the sum of the angles must equal
.
Example Question #2 : Angles
Are
and supplementary angles?Yes
No
Not enough information
Yes
Since supplementary angles must add up to
, the given angles are indeed supplementary.Example Question #1 : Understanding Complementary And Suplmentary Angles
Which of the following angles is complementary to
?
Two complementary angles add up to
.
Example Question #1 : Angles
What angle is supplementary to
?
When two angles are supplementary, they add up to
.
Solve for
:
Example Question #3 : Angles
Which of the following angles is coterminal with
?
For an angle to be coterminal with
, that angle must be of the form for some integer - or, equivalently, the difference of the angle measures multiplied by must be an integer. We apply this test to all five choices.
