Ch. 1-11 Test and Corrections

On Friday you received your Chapter 1-11 Test.  Test corrections are due on Monday, unless you need extra help- in which case you should come see me at lunch on Monday, and you can work until Tuesday to complete corrections.  PLEASE SEE ME if you are having trouble with your corrections!

Extra Credit Assignment

Hi everyone, please remember that your extra credit drawing is due tomorrow.  The more creative and detailed, the more points you will receive toward your project average.  All missing assignments are due tomorrow as well.

Chapter 10 Review and Extra Credit Project

Today we celebrated Pi Day and the culmination of Chapter 10 by working on an extra credit project.  Your project is to create a drawing using circles, lines, and parabolas and labeling each equation of each figure that you draw.  This extra credit project is due on Friday and points will be awarded based on creativity and detail.

Also, please visit http://www.classzone.com/cz/books/geometry_2007_na/crossword.htm?id=xword_ch10 and complete the Chapter 10 Crossword puzzle.  Either email me a screenshot of your results (email to bergerj@nestmk12.net) or print out your finished puzzle.  This is due by tomorrow.

Please also study for you Cumulative Test which will be on Wednesday (Short Response) and Thursday (Multiple Choice).

11.6- Area of a Regular Polygon

Since I know we covered a lot today about the area of regular polygons, please take a look at these videos for a more complete understanding of the material:
http://www.brightstorm.com/math/geometry/area/center-and-apothem-of-regular-polygons
http://www.brightstorm.com/math/geometry/area/area-of-regular-polygons

We will continue talking about this on Monday

Tonight's homework is P. 765-766 #7, 11, 15, 18, and 21

You will have your next Cumulative Test next week on Wedensday (Free Response) and Thursday (Multiple Choice).  Remember this covers everything since the beginning of the year.

Locus

Yesterday and today we talked about the six fundamental loci constructions.  We also learned how to find the locus of a combination of conditions.  See this video for help on the concept of a locus (keep in mind, we are only concerned with 2-dimensional loci at this point): http://www.brightstorm.com/math/geometry/circles/locus-and-definition-of-a-circle-and-sphere

For tomorrow, please complete your Chapter 10 Study Project.  See the previous post for the terms: http://nest8thgrademath2010.blogspot.com/2011/03/chapter-10-study-project.html

10.7- Graphing Circles

Today we practiced graphing circles, both by hand and in our graphing calculators.  We were also introduced to the concept of intersection circles and how this relates to loci- which we will continue discussing tomorrow.

Tonight's homework is P. 703 #23,25,26,31, and 33

10.7- Writing Equations of Circles

Today we learned the standard equation of a circle and how to write equations given the center and radius or enough information to find either of these.  If you were absent, you can find more information about finding the equation of a circle here: http://www.brightstorm.com/math/geometry/pythagorean-theorem/equation-of-a-circle

Tonight's homework is P. 702-703 #3,4,7,11,14,16,17

Chapter 10 Study Project

Your chapter 10 Study Project will be due in one week, Thursday, March 10.  Here are the terms so that you can get started tonight- please remember to include diagrams!:

Tangent (include any theorems and properties)
Central Angle (include its corresponding arc measure)
Chord (include properties of chords from section 10.3)
Inscribed Angle (include how to find its measurement)
Inscribed Polygon (include what you know about inscribed right triangles and quadrilaterals)
Angle Formed by a Tangent and Chord
Angles Inside the Circle Theorem
Angles Outside the Circle Theorem
Segments of Chords Theorem
Segments of Secants Theorem
Segments of Secants and Tangents Theorem
Standard Equation of a Circle
Locus
Area of a Regular Polygon

10.6- Find Segment Lengths in Circle

Today we looked at the relationships between the segments lengths in a circle, specifically of chords, secants, and tangents.

Tonight's homework is P. 692-694 #3,6,9,14,16
Tomorrow we have a quiz on Chapter 10.1-10.6 (Everything we have learned about circles so far).  Please review these sections and be sure that you know all of the properties of circles that we have learned so far.

11.4 Part 2 and 11.5- Angles Relationships in a Circle

Today we learned about inscribed polygons of a circle and other angle relationships of a circle, namely Angles inside a circle and outside of a circle.

Tonight's homework is P. 676-677 #13,15,19,21,23 AND P. 683-684 #3,6,9,11, and 13
