Congratulations on completing the first quarter of the 07-08 school year!

One down, three to go! Of course, there is no rest for the weary. Now that mid-term exams are behind you, it is time to look forward to the next nine weeks. Enjoy your Friday off because you are going to have to hit the ground running over the weekend to prepare for your first grade of the new nine weeks. Yes, it is the Circle Test. Yes, it is online. And yes, you can download your very own copy at msichan.com. Have fun!

Circle Practice Test

• go to msichan.com to download
• test will be on Monday
• I would put together a study group for the weekend, maybe meet at the library or Starbucks or Barnes and Noble.....

Be sure to practice the practice mid-term a few more times before Thursday!

Be sure to complete your reference sheet!

Be sure to go to my website, msichan.com, to view the exam schedule. Know what time each exam begins and ends.

If you are late to my exam, I will lock you out. Don't be late!

Good Luck on your first 2 exams tomorrow!

Create a scrap paper packet for your mid-term exam

• staple about 4-5 sheets (you could have more if you like depending on how big you write) of paper together
• write your name in the upper right hand corners of each paper
• underneath your name, write your period
• underneath the period, write "October 24, 2007"
• underneath the date, write "Geo Hon Mid-Term Exam Scrap paper"
• highlight the heading
• I will be collecting this scrap paper packet from you tomorrow!

Create a reference sheet to use on your mid-term exam!

• front side only!
• regular notebook size paper: eight and a half inches by eleven inches
• you canuse computer paper if you like
• must be handwritten (no typing!)
• what can you write on it? anything you want!
• MUST have your name (highlighted) in the upper right hand corner
• this reference sheet will be worth extra credit--more details to follow tomorrow!

Other Circle Stuff

Aim: to determine the lengths of 2 intersecting chords

If 2 chords intersect in a circle, then the product of the lengths of one chord is equal to the product of the lengths of the other chord.

Because today's lesson is not found in your book, I am making up some of my own problems for you to try this weekend. Have fun!

Chords AB and CD intersect in a circle at X (YES! Draw a picture first!). Find the value of x and the lengths of each missing segment given:

1. AX=4, XB=3x, CD=2 and XD=8
2. AX=2x+1, XB=5, CX=10x+7, and XD= 8.
3. AX=4x, XB=3x, CX=2, and XD=x+5
4. AX=18x, XD=x, CX=4, and XD=1/2x + 5

Be sure to complete the Mid-Term Practice Exam on your OWN paper! Yes, that means that you should fold your paper into boxes to make your OWN answer sheet.

I will be walking around to observe your completed work. Your answer sheet should look like my solution page. Your answers should be highlighted. I should be able to follow your work to see how you arrived at an answer.

Do NOT, I repeat, do NOT, just copy my work onto your own paper! If you don't know how to do a particular problem, write out the problem and nothing else. Put a big red question mark (?) in that box so that when I ask if there are any questions, you will be able to quickly ascertain which questions you don't understand.

You should complete the mid-term practice exam at least 3x this weekend!!!!!!!!

That's it. Have a PG-13 weekend!

Practice Mid-Term Exam

• (1-78) all
• problems 79-85 are from Ch. 7 so you won't be able to complete those problems
• For 86-100, I want you to make a Quadrilateral Flowchart. Start by drawing a big box at the top of your paper. Inside of it, I want you to write the word "Quadrilateral". Underneath the word "quadrilateral", you should write its definition: "a four-sided figure"
• There should be 3 branches coming off of the "Quadrilateral" box.
• One should be a "Parallelogram" box. One should be a "Kite" box. The other should be a "Trapezoid" box.
• Don't forget to put the definitions of the words underneath the word.
• In each box, you should list the special properties you discovered. Hint: there are 4 special properties for a parallelogram.
• There should be a branch coming off the parallelogram box labelled .....?......
• Hint: there are some special parallelograms!
• Write the definitions and special properties of those figures, too!

Don't forget to practice doing the Ch. 4/6 Practice Test (if you haven't done so already, you may download this practice test and the solutions from msichan.com) !!!! You will be given 70 minutes to take the test. The last 20 minutes will be devoted to learning lesson #5.4. That means that I will not go over any of the above HW answers until Tuesday. Therefore, you should pace yourself and prioritize accordingly. Perhaps you could do:

• the practice test on Friday night and #5.1 and #5.2.
• On SaturDAY, you could do the practice test AGAIN. Then do #5.3.
• On Saturday NIGHT, you could do the practice test again and do PH #3.3
• On SunDAY, you could do the practice test again. Then do PH #4.5
• On Sunday evening (after watching football), you could do the practice test one more time for good measure. Then do PH #5.5.
• But of course, this is just a suggestion. You do what you want. Just remember, you play the way you practice. The more you practice, the better you play. Monday is the Super Bowl. You can either bring your "A" game or you can fumble and lose the game. Either way, the choice is yours.

Have a PG-13 Geometry filled weekend!
