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.

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

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!

1) Line (Reflection) Symmetry: A figure has Line (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. I never realized I wuz so good lookin’! Yeah, I know… right?!

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! 1-102

Rotational Symmetry: 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. Geometry really turns me on… (and on… and on… and on… and on.. and on… and…)

Rotational Symmetry: 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. I’m really enjoying this to a very high degree! (Yuk, yuk…)

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

Today’sObjective: 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. * SWBAT = S tudent W ill B e A ble T o 2 Lessons Today Participation Quiz Today Teamwork important

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.

Remember... It’s hip to be a square!

Boot-Up / 6 min. 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: a)Perimeter? Area? The photograph of the tough-looking team below measures 8” x 10”.

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. 6)Failure to follow these instructions will result in a failure on the test. 7)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! Graph Paper / Tracing Paper
