Today and yesterday, we started chapter 8, discussing similar figures... specifically, similar polygons and triangles. We learned the three theorems for proving triangle similarity. For more help on this topic, read sections 8.1-8.3 in your textbook.
We're having a review exam this thursday on chapters 4-6. Study up!

Homework:
none
Over the past two days, we've been reviewing chapter 7, with a HEAVY emphasis on lesson 7.7 - Areas of sectors and segments. Today, we took our final chapter 7 test. Please see Mr. Jones about making this test up if you were absent on Friday. On Monday, we'll start Chapter 8 on similarity and proportions.
GO HEELS!!!

Homework:
Watch the stock market!
The past two days, we've been working on chapter 4, learning about the mathematics behind financing a new car. Today, we researched the stock market and "bought" our mock-stocks based on our regression equations attained from our stocks' recent performance.

Today, we learned how to calculate the area of circles, and we were introduced to sectors and segments -- pieces of the area of a circle. We covered how to calculate their area using fractions and how to use part+part=whole equations to solve problems.
For more help on this topic, read section 7.7 in your textbook. We will have our final Chapter 7 test this coming Friday. ***Reminder! Corrections for our first Chapter 7 test are due this coming friday. Don't be late!***

Today, we "officially" learned the Pythagorean Theorem. (We have been hinting at it for a while.) We also learned how to correctly identify the legs and hypotenuse of any right triangle, in order to write our Pythagorean equations correctly.
For more help on this topic, read section 7-2 in your textbook.

GEOMETRY
Homework:
None! Study for chapter 6 test tomorrow!!!
Tips:
1) Study and memorize at least the 5 parallelogram properties, as well as the 2 rectangle properties and 3 rhombus properties.
2) Review parallel lines (chapter 3), especially alternate interior angles.
3) Review triangle rules, especially Triangle Angle Sum Theorem (3 angles = 180)
Extra practice:
p.342 chapter test
#1-3
#8-15
#17-19
(solutions below... try not to look until you're done!)
1. Trapezoid - only one pair of parallel sides (DRAW THESE! DON'T JUST GUESS!)
2. Kite - 2 pairs of congruent, intersecting sides
3. Parallelogram - 2 pairs of opposite congruent sides
8. x=100, y=50, z=40 (look for the isosceles triangles)
9. x=57, y=57, z=66 (diagonals of a rhombus bisect the angles they enter)
10. x=6, y=5 (diagonals bisect each other... 4x-4=3x+2)
11. x=36, y=108, z=72
12. Yes - parallelogram prop 4
13. Yes - 5th (extra) method of proving a parallelogram
14. Yes - parallelogram prop 2
15. Yes - parallelogram prop 3
17. x=2, y=1
18. 90, 30
19. 50,30
Hope that helps!
