Review Sheet in class and start Closure Problems
HW: STUDY FOR CHAPTER TWO TEST
BONUS Closure assignment:
All Chapter 2 Closure problems starting with 2-123 and ending with 2-130

Topics to Review for Chapter 2 Test:
  • Angle Relationships and their Rules
    • Straight Angle Pair (windshield wiper) - Supplementary
    • Vertical Angles - Congruent
    • Corresponding Angles - Congruent
    • Alternate Interior Angles - Congruent
    • Same-Side Interior Angles - Supplementary
  • Are the lines parallel?
  • Areas of:
    • Triangles = (1/2)(b)(h)
      • Drawing in the height - train method
      • Height must be:
        • 1. Coming down from the opposite vertex (the vertex across from the base)
        • 2. Forming a right angle at the base.
    • Parallelograms = (b*h)
      • Same formula as a rectangle. But remember the HEIGHT in a PARALLELOGRAM is not a side length, it is an invisible line inside of the parallelogram that forms right angles. It is only an actual side length if you parallelogram is a RECTANGLE.
    • Trapezoids = (1/2)(b1+b2)(h)
  • Pythagorean Theorem (ONLY) works for right triangles.
  • Triangle Inequality

Week 5: Alg. II & Alg. II/Trig

Monday 9/17: 
Review: Correlation Coefficient, Absolute value equations and inequalities
Notes Page 104
Page 108: Is it a function? Is its inverse a function?

(Vertical line test to see if it is a function. Horizontal line test on the same graph to see if its inverse will be a function.
On a table, we want to see no multiple x's leading to different y's. In the inverse, the x's and y's are switched, so we can look at a table of an original function and make sure no y's are leading to different x's to make a conclusion about whether or not the inverse is a function.)

Hi All -

This is my blog site for our class, and I will be posting information on here that I'd like to communicate with the whole class. Check the site often and I encourage you to ask questions by leaving a comment.

Have a great Spirit Week :)

Monday
Class: Transformations and Quiz Review
HW: Study for Quiz 2

See http://www.purplemath.com/modules/fcntrans.htm for summary of transformations. Also http://people.richland.edu/james/lecture/m116/functions/translations.html. Be comfortable with these "shifts" for Quiz 3.

We will be having our second quiz on Tuesday.
No calculators will be used on this quiz.
Topics for this quiz include solving absolute value problems (remember to test your solutions to make sure some solutions are not lying to you!!!), simplifying expressions with exponents, and algebraically finding the domain, and graphically finding the range. 
UPDATE: Also rational/irrational number vocabulary will be on Quiz 2.

Notes on Domain and Range:

Domain: Algebraically - What values of x are "cool" with the rules of math? The two rules we look for are:
dividing by zero (this is undefined - a vertical asymptote) or,
taking the square root of a negative number (this gives an imaginary result)
What are the "allowed" values of x? What are we able to input?
Vertical asymptotes will interrupt the domain.
Graphically - Where does the function exist horizontally (described by x values)?

Range: Algebraically - What values of y can I get back, as an output?
(This is harder to solve for algebraically, so we can look at the graph.)
Graphically: Where does the function exist vertically? (described by y values)
Horizontal asymptotes will interrupt the range.

Asymptotes are lines that are often invisible in the graph - think of them as invisible walls that the function never crosses.

GEOMETRY CHAPTER 1 TEST - THIS FRIDAY! 9/14/12

Hello and welcome to the blog site for Geometry with Ms. Liefland at Harper. Check here for homework updates, class announcements, and test/reference information. Also feel free to leave any comments for me and your classmates to respond to.

Hope everyone had a good weekend. Parents - also feel free to check the blog for information about your child's Geometry class.

Monday 1.2.5
Classwork 1-87 through 1-90
Handout (HELPFUL): http://www.cpm.org/pdfs/stuRes/GC/chapter_01/GC_1.2.5.pdf
Homework: Review Methods & Meanings "Parallel and Perpendicular Slopes" and do 1-93 and 1-95

In the Chapter 1 "Closure" section in the textbook, part 2 ("Making Connections") offers a list of vocabulary that is essential to know in Chapter 1. In addition to this list, we have added: perpendicular bisector, isosceles triangle, angle bisector, line/line segment/ray, central angle, interior angle, equilateral, and we know two formulas:
- The sum of all the interior angles in a triangle is 180. (This means the three angles in a triangle add up to 180. They are not necessarily 60-60-60, though, unless the triangle is an equilateral triangle.)
- The measure of a central angle (think of spokes on a wheel - the central angle is the degree between the spokes coming from the center to two adjacent vertices) can be multiplied by the # of sides to equal 360. We can only use this formula with regular polygons. (Central Angle)x(# of sides)=360
This makes sense to us visually because all of the central angles together form a full circle, which measures 360!

Remember our grouping of these terms:
Types of Transformations
Rotations
Reflections
Translations
