Honors Geometry 5/6 Sept 2012
1) Summarize your notes from yesterday on the
bottom of your Cornell notes.
2) Place binder and text on your desk.
3) Warm-up: Use same sheet as yesterday.
Keep in left side of folder for the week.

Students will be able to be able to identify,
sketch and label, midpoint, lines and angles.
Students will take notes and work
collaboratively.
Due TODAY- ART PROJECT
Place it on top of your group folder.
Tutoring
Monday 3 – 3:45
Thursday 1:30 – 2:15
HOMEWORK DUE Friday:
pg. 33 +: 18- 32 evens
(use graph paper, use KWHCC– write basic info)
pg. 37: 1 – 6 all
If you have 3rd edition- find assignment from
online textbook. See me if you have questions.
HOMEWORK NORMS
Homework is due at the beginning of class
LATE homework will be accepted for no more than 70%
credit. You must come in during a scheduled
tutoring session and explain the homework, within
ONE WEEK of the original due date.
Homework will be graded based on completion.
NORM-- write basic info/ show work
If you don’t know what to do,
WRITE down the basic info and what you are trying to find
WRITE what you tried to do to solve and
WRITE a question about your “point of confusion”
If you follow these steps, showing me you made a good
effort to complete your homework, you will get full points.
Use complete heading on ALL work submitted
for this class. Work with an incomplete
heading will be considered LATE!
(i.e. LATE POLICY will apply!)
KWHCC– handout
- problem solving strategy
KEEP IN front of NOTEBOOK
Geometry Symbols– reference sheet (yellow)
what jobs require you to learn
naming/ labeling?
Take notes……finding midpoint
Watch video:
http://www.khanacademy.org/math/algebra/linearequations-and-inequalitie/v/midpoint-formula
FORMULA for midpoint:
If the coordinates of A and B are ( x1, y1) and ( x2, y2)
respectively, then the midpoint, M, of AB
is given by the following formula (Midpoint Formula).
practice
1) Write the midpoint formula on top of your paper.
2) Plot the points on graph paper.
3) Find the midpoint graphically and then algebraically,
showing your set up for each.
(1) ( 1, 2) and (3, 6)
(2) ( -2, -3) and (4, 5)
(3) (-3, 2) and (3, -2)
(4) ( -3, -5) and (0, 4)
Be ready to present your work to the class.
THINK--complete the section 1.2 anticipation guide
Pair: Chat with your group. Do you agree?
Now turn to pages 38 – 39
and see if you need to revise your answers.

Angle Vocabulary- summarize in your
vocabulary section
• An angle consists of two
different rays that have the
same initial point. The rays
are the sides of the angle.
The initial point is the vertex
of the angle.
• The angle that has sides AB
and AC is denoted by BAC,
CAB, A. Point A is the
vertex
vertex of the angle.
C

B

Ex.1: Naming Angles
• Name the angles in the
figure:
SOLUTION:
There are three different
angles.
• PQS or SQP
You should not name any of
• SQR or RQS
these angles as Q because
• PQR or RQP
all three angles have Q as their
P
S
Q
R
vertex. The name Q would
not distinguish one angle from
the others.
Note:
• The measure of A is denoted by mA. The
measure of an angle can be approximated
using a protractor, using units called
degrees(°). For instance, BAC has a measure
of 50°, which can be written as
mBAC = 50°.

more . . .
Angles that have the same
measure are called
congruent angles. For
instance, BAC and DEF
each have a angle
congruency mark, so they
are congruent.

Note – Geometry doesn’t use equal
signs like Algebra
MEASURES ARE EQUAL
ANGLES ARE CONGRUENT
mBAC = mDEF
BAC  DEF
“is equal to”
“is congruent to”
Note that there is an m in front when you say equal to
“the measure of the angle…… equals…..”
The congruency symbol  says “same shape (angle)”
“same size”. “Angle BAC is congruent to…..”
practice– in your notes….
Name each angle in as many different ways as
you can: A

Work with your group to complete TWO
handouts1) Measuring Angles
2) Lesson 1.2 Poolroom Math
Be prepared to share your work with the class.
Once your group is FINISHED, I will ask each
group to prepare a POSTER showing the
solution to one of the problems.
