2. The photograph of the tough-looking team below measures 8” x 10”. Ms. Guice wants us to make an enlargement to frame and put in the front entrance. If we enlarge the photo by a scale factor of 2, what will be the new: Perimeter? Area? Boot-Up 8.23.13 / 6 min.

3. TSW Read Lesson Intro. TTW: Explain that TSW be responsible for answering 3 questions at end. TTW: a) show agenda b) H/O Rsc. Pg. 1.2.6 1-99 – 1-102.

4. Today’s Agenda • 1) You will work in pairs on problem #s: •  1- 99  1-100 • 1-102 • Learning Log. • Read M&M p103 TTW will give you “Red Light”or “Green Light” as you complete each problem. Copy This

7. What is a Regular Polygon? It is a polygon in which: 1) All sides are congruent () to each other; and 2) All angles () are congruent () to each other.

8. This is highly irregular… Regular Polygon: A polygon in which all sides & angles are congruent! Example: Regular Hexagon Irregular Hexagon

9. Which of the shapes on your Resource Page are Regular Polygons? What do you notice about the Regular Polygons & the # of lines of symmetry each has? A Regular polygon has the same # of lines of symmetry as it has sides! What else does a regular polygon have that is equal to its # of sides? Angles!

11. I never realized I wuz so good lookin’! Yeah, I know… right?! 1) Line (Reflection)Symmetry:A figure hasLine (Reflection) Symmetry if a line can be drawn through it so that each half is a mirror image of the other. 2) Line of Symmetry:The line along which a figure can be folded so that the 2 halves match exactly.

13. 1-102 The book said this is a Regular Polygon with 10 sides. Therefore, how many lines of symmetry must it have? If it is a Regular polygon, then it must have the same # of lines of symmetry as it does sides! In this case, 10!

14. 1-100

15. Geometry really turns me on… (and on… and on… and on… and on.. and on… and…) RotationalSymmetry: A figure has rotational symmetry if -- after the figure is rotated (turned) about a point of less than a full (360°) turn -- the figure appears the same as when in its original position.

16. I’m really enjoying this to a very high degree! (Yuk, yuk…) RotationalSymmetry: To determine the # of degrees a figure must turn to show rotational symmetry: Divide 360 by the # of turns the figure must make to return to its original position.

21. Put your initials in the proper place below. Boot-Up 8.27.13 / 6 min. Has ≥ 1 Dog Has ≥ 2 Siblings

22. Mathematical Product: SWBAT:* Learn what qualities make shapes alike & what makes them different. Mathematical Practice / CCSS Standard: SWBAT: 1) Make sense of problems, 2) Persevere; 3) Attend to precision as they describe common shapes & their characteristics. Today’s Objective: *SWBAT= Student Will Be Able To 2 Lessons Today Participation Quiz Today Teamwork important

23. Resource Manager: Make sure to get all of the supplies & call the teacher over, if needed. Take shape inventory at beginning & end. Make sure all shapes are returned to bucket. Facilitator: Make sure that everyone can participate & that no one dominates the process. Recorder/Reporter: Make sure that everyone can reach & see the Venn diagram & the shapes. Record shape placements / present findings at end of lesson. Task Manager: Make sure each team member justifies statements & decisions.

24. Remember... It’s hip to be a square!

26. y Look at the graphed red line. What is the y-intercept? What is the slope? Write the equation of this line in slope-intercept form. Write the equation of a line that is parallel to this line, with a y-intercept of 4. 6) Write the equation of a line that is perpendicular to this line, with a y-intercept of -2 I II x Boot-Up 8.28.13 / 6 min.

30. The photograph of the tough-looking team below measures 8” x 10”. The enlargement we hung in the lobby was so popular, Ms. Guice now wants us to make an even bigger enlargement to frame and put in the atrium. If we enlarge the photo by a scale factor of 4, what will be the new: Perimeter? Area? Boot-Up 8.28.13 / 6 min.

31. 1) You may use a calculator, but you MUST SHOW ALL WORK for full credit. You will not pass the test if all you show is the final answer. 2) You may not speak or make any other type of noise during test. 3) You must keep your eyes on your own papers. 4) You will have the entire block to complete the test. If you finish early, raise your hand silently & teacher will give you assignment. Failure to follow these instructions will result in a failure on the test. You have all the skills & knowledge you need to perform well on this test. Just remember what we discussed in class & do your work slowly & carefully. Check your work several times. Good luck!
