2.6- Prove Statements about Segments and Angles

Today we began writing proofs about the congruency of segments and angles.  Please remember that writing proofs takes practice because forming a logical argument does not always come easily to many of us.  Do not discouraged, and know that we will be writing many proofs about many geometric concepts throughout the year.

Tonight's homework is P. 116-119 #4, 12, 16, 17, 18, 22, 31

2.5- Reason using Algebraic Properties

Today we learned how to use Algebraic Properties to apply deductive reasoning to form logical arguments.  We learned the Addition Property, Subtraction Property, Multiplication Property, Division Property, Substitution Property, Distributive Property, Reflexive Property, Symmetric Property, and the Transitive Property.  Please practice these properties because we will use them throughout the school year.

Tonight's homework is P.109-111 5,9,14,17,21-25,33,39 and we have a QUIZ tomorrow on sections 2.1, 2.2, 2.4, and 2.5 in the textbook.

Please do practice 2.5 in the eworkbook http://www.classzone.com/cz/books/geometry_2007_na/resources/htmls/ml_hsm_geom_eWorkbook/index.html
and do the section quizzes to prepare for the quiz tomorrow.

2.4- Use Postulates and Diagrams

Today we learned about how to apply postulates about point, lines, and planes to interpret and sketch diagrams.

Tonight's homework is P. 99-102 #3,4, 6-24 all, 46, and 47

Please visit Section 2.4 in the eworkbook for more practice: http://www.classzone.com/cz/books/geometry_2007_na/resources/htmls/ml_hsm_geom_eWorkbook/index.html

Your next quiz will be on Sections 2.1, 2.2, 2.4, and 2.5 on Wednesday, September 29.

2.2- Analyzing Conditional Statements

Today we learned about conditional statements, including the converse, inverse, and contrapositive of a statement and whether or not it can be written as a biconditional statement.  These concepts will be reviewed throughout the year and applied to theorems and definitions and proofs that we will learn in Geometry this year.

This weekend's homework is P. 82-85 #3-15 odds, and 19-27 odds.  Also, your Geometric Construction Book Part 1 is due on Monday.  Please review the directions and look at P. 33-34 in your textbook for further help with creating the required constructions.

Please use this animation to help you analyze conditional statements: http://www.classzone.com/cz/books/geometry_2007_na/resources/applications/animations/2_1_2.html

2.1- Inductive Reasoning

Today we described patterns and made conjectures using inductive reasoning.

Tonight's homework is P. 75-78 #7,13,15,21,29,39,40

1.7- Perimeter and Area of Polygons and Circles

Please review the formulas for area and perimeter of rectangles, triangles, and circles.  Today, we applied the distance formula to find the perimeter of polygons.

Tonight's homework is P. 52-55 #5,7,13,17,19,21,25,31,35.

Geometric Construction Book Part 1

Today we learned about our Geometric Construction Book Project.  We learned how to do the first four constructions: copy a segment, bisect a segment, copy an angle, and bisect an angle.  Please know that for you book, you need to draw the construction and write detailed step-by-step instructions on how you made the construction.  For help, you can see P. 33-34 in your textbook.  The first part of the construction book is due on Monday, September 27, 2010.

1.6- Classifying Polygons

Today we reviewed/learned different ways to classify polygons.  Please be sure you know what a polygon is, how to name them, the difference between convex and concave polygons, equilateral, equiangular, and regular polygons.

Tonight's homework is P. 44-45 #3, 5, 7, 11, 13, 17, 29, and 37

Check out this PacMan animation to practice classifying polygons http://www.classzone.com/cz/books/geometry_2007_na/resources/applications/animations/6_1.html

1.4 and 1.5 Angle Classification and Angle Relationships

Today we reviewed various angle classifications (acute, obtuse, right, straight) and learned new angle relationships (congruent, complementary, supplementary, linear pairs, and vertical angles).  These are fundamental to geometry and we will continue using these throughout this year.

This weekend's homework is P. 29-30 #21-47 odds only, AND P. 39-40 #9-42, every 3rd problem (ie.9,12,15,18, etc).

If you do not know how to use a protractor or need a review, please visit this animation: http://www.classzone.com/cz/books/geometry_2007_na/resources/applications/animations/g6_9_2.html

1.3- Midpoint and Distance Formulas

Today we investigated how to find the midpoint and length (distance) of a segment given its endpoints.  Please recall the use of averages and the pythagoren theorem when using the formulas.

You homework is P. 19-22 #3-48, every third problem (ie. 3,6,9,12, etc.) and problems 55-57 on the same page.
