Chapter 8 Review for Test

Find the sum of the measures of the interior angles of each convex polygon. 

S = (n-2)180 --> n stands for the number of sides; S stands for sum

1.decagon   

2. 16-gon   

3. 30-gon

The measure of an interior angle of a regular polygon is given. Find the number of sides in the polygon.

If an interior angle measure is 150, the exterior angle angle is 30 degrees. 360/30 = 12; dodecagon

or 150n = (n-2)180

7. 150   

8. 160   

9. 175

Find the measure of each exterior angle for each regular polygon.

360/number of sides

4. 12-gon 

5. hexagon   

6. 20-gon

5	Student worked quietly and independently. Student completed Math League Contest and worked independently on Geometer's Sketchpad activities with little assistance from others/teacher. Excellent use of time-management and problem-solving skills.
4	Student was communicating with others at times. Student completed Math League Contest and worked independently on Geometer's Sketchpad activities with assistance from others/teacher. Good use of time-management and problem-solving skills.
3	Student was communicating with others many times. Student completed Math League Contest and worked on Geometer's Sketchpad activities with assistance from others/teacher. Could show better use of time-management and problem-solving skills.
2	Student was communicating with others throughout the lab visit. Student completed Math League Contest and worked on Geometer's Sketchpad activities with a lot of assistance from others/teacher.  Lack of time-management and problem-solving skills.
1	Student was off task and received multiple reminders about appropriate behavior. Did not use time wisely to complete the assignments.

Activity 1: Math League Contest
Log on to the Math League Contest. Be sure to read all directions on how to enter your answers correctly. If you forgot your password or log in, raise your hand and wait for Mrs. Smith to give it to. You will need an activation code in order to take the test. This will be posted on the wall once everyone is in the lab and logged in. Once you begin the test, you will have 30 minutes to complete it. You may use scratch paper and a calculator. When the test results are in, students who receive credit for correct answers will receive extra credit points toward their homework grade.

Activity 2: Triangle Inequality Activity - Geometer's Sketchpad - you will be turning in an index card with this activity. One side will include a table and the other side will include the answers to questions 1-3, located after step 10. 

Before you begin this sketch go to the Edit Menu and choose Preferences and under the Text Tab make sure that For All New Points is checked then click on OK.

Step 1            Select the Straightedge Tool and hold down and select the segment icon.  Then in the white space construct a triangle.

 Step 2            Using the Selection Arrow Tool notice you can move any of A, B, or C by clicking on them and dragging with your mouse.

 Step 3            Using the Selection Arrow Tool select segment AB and from the Measure Menu choose Length.  Click in the white space so that no items are selected.

 Step 4            Select segment BC and from the Measure Menu choose Length.  Click in the white space so that no items are selected.

 Step 5            Select segment AC and from the Measure Menu choose Length.  Click in the white space so that no items are selected.

 Step 6            From the Number Menu choose Calculator.  Click on the measurement for AB in the white space, the + sign of the calculator , click on the measurement for AC in the white space, and then click on OK.

 Step 7            Record your initial measurements in the table. (Create your table on your index card. Be sure your name is on the index card before you turn it in.)

AB
AC
AB + AC
BC

 Step 8            Drag A so that the shape of the triangle changes and record your measurements.

 Step 9            Drag B so that the shape of the triangle changes and record your measurements.

 Step 10          Drag C so that the shape of the triangle changes and record your measurements.

Question 1

Using the data you have collected, how does the measurement of AB + AC compare to BC?

 Question 2

Click on A and drag until the measurement of AB + AC = measurement of BC.  What do you notice?

 Question 3

Without taking any additional measurements or doing any calculations, what do you think would be true about the measurement of BC + AC and the measurement of AB?

  Step 11          Go to the Number Menu and select Calculator and select the measurement of BC in the white space, the + key on the calculator, the measurement of AC in the white space and then click on OK.  Test your conjecture from Question 3.

Activity 3: Use the practice links on the side of the blog - take quizzes, watch videos, etc.
Rotate triangles - practice with geometric mean

We will cover 7.3 on Monday.

Computer Lab Activities

READ ALL OF THE DIRECTIONS CAREFULLY TO RECEIVE FULL CREDIT FOR TODAY'S LAB ACTIVITY.

1.       Complete the Geometer’s Sketchpad Activity – Triangle Side Lengths
Save your activity in the Y Drive under !Geometry with your last name, first initial, 7.1 
Example: SmithC7.1
***** A few minor changes to note in the directions:
--> Step 2 says "HIDE LINES", when you get to this step, the option is for "HIDE STRAIGHT OBJECTS"
--> Step 4 says, "From the Measure menu, choose Calculate." CALCULATE is actually found under the NUMBER menu.

2.      Complete the Geometer’s Sketchpad Activity - Dilations. Save your activity in the Y Drive under ! Geometry with your last name, first initial, 6.7 Example: SmithC6.7

Draw a dilation of the polygon with the given vertices using the scale factor k.

A (-3,6) B (0,0) C (-6,0) k: 2/3

STEP 1 Draw a triangle

From the Graph menu, choose Define Coordinate System to set the coordinate system in the drawing area. From the Graph menu, choose Plot Points. Select the points the construct segments.

STEP 2 Draw a dilation

Select points A, B, and C and the segments.  From the Transform menu, choose Dilate. Enter your scale factor. Use the Text tool to label the vertices of the dilated triangle P, Q, and R.) (It's ok if the dilation renames your triangle A' B' C'.)

STEP 3 Measure side lengths Measure the lengths of AB, BC, CA, PQ, QR, and PR.

Select points A and B. From the Measure menu, choose Distance. Repeat to find all of the segment measures.

3.      Determine the type of triangle by graphing it in Sketchpad.

Use Sketchpad to graph points A, B, and C using the coordinates given. Decide whether triangle ABC is acute, right, or obtuse. Write the answers on looseleaf with your PSM heading on top.

1.      A (1,5), B (1,1), C (6,1) ­______________________________

2.      A (2,4), B (4,1), C (7,1) ______________________________
