Statement
Supplementary angles have a sum of 180°.
Adjacent angles share a common ray.
Vertical angles are complementary.
Vertical angles are congruent.
You can ALWAYS name an angle with its
vertex.
Complementary angles have a sum of 95
degrees.
After Lesson
(Agree or
Disagree)
Standard: Use facts about supplementary, complementary, vertical, and
adjacent angles in a multistep problem to write and solve simple equations
for an unknown angle in a figure. [7-G5]
Part A—What is an angle and how do we name an angle?
An angle is a figure formed by two noncollinear rays that
have a common endpoint.
Given the angle below, label the sides and the vertex.
Using the example above, name the angle below several different ways.
Use the figure to the right to answer the following.
a. Can you name vertex W to name any angle in
the figure to the right? Why or why not?
b. What are other names for <1?
c.
What are other names for < 2?
d. What is the name of the largest angle with “W”
as a vertex?
Special Types of Angles
a.
Name the two adjacent angles using three
letters.
b. Name their common ray.
c.
What large angle do the two adjacent
angles make?
Determine whether <1 and <2 are adjacent in the following figures. If not, please state why.

Complementary Angles
Note: Complementary angles DO NOT need to have a common side or
even the same vertex; however, they can.

What is the measure of <TZU?
Supplementary Angles
?
What is the m <PHQ?
Vertical Angles
Note: Vertical angles DO NOT add up to a certain sum like
complementary and supplementary angles. Instead they are congruent---which means they have the same measure.

Snowball fight Activity---In this activity, you will take the ball of paper on
your desk and throw it at any student (not in the face or close to the face).
You will continue to pick up the snowballs until I say stop. Once I say
stop, you must unravel your snowball and decide what type of angles are
on your paper. “Supplementary, Complementary, or Vertical” You will
then stand and show the class. You must explain why you think your
angles are _____________________. If you do not have a paper in your
hand when I say stop, you will find one on the floor and pick it up. Have
Fun!!!!

If we know the relationship between two angles, we can set up an ______________________ to
solve for unknown values. Find the value of x and then each angle measure.

During: 15 problems involving problem solving with special types of
angles will be placed randomly around the room. Pairs will be stationed
at different groups. Pairs will solve the problem and find the problem
containing their answer. The answer will be on another problem in the
room. Pairs must then walk to that particular problem , solve it , and walk
to the problem containing that particular answer. Pairs will move from
problem to problem depending on the answer they get. This will
continue until they go all the way back to their original problem. This is
called a math scavenger hunt. I will help all pairs that are struggling.
