EXTRA CREDIT ALERT!!!!

• if your grade is on life support and you need a "jump", here it is....

CREATE A POWERPOINT PRESENTATION:

• must include a title page (example: Writing Equations for Dummies by: John Smith)
• given triangle JIM with coordinates J (0, - 6), I (3, 6) and M (12, 0)
• give DETAILED STEP-BY-STEP instructions on how to:

1. write the equation of a line of the perpendicular bisector of JI
2. write the equation of a line of the perpendicular bisector of IM
3. write the equation of a line of the perpendicular bisector of JM
4. write the equation of a line of median JA
5. write the equation of a line of median IB
6. write the equation of a line of median MC
7. write the equation of a line of altitude JX
8. write the equation of a line of altitude IY
9. write the equation of a line of altitude MZ
10. find the coordinates of the circumcenter
11. find the coordinates of the orthocenter
12. find the coordinates of the centroid

• BE CREATIVE!!!!
• use colors in your step by step instructions
• pretend I know absolutely nothing. that means you MUST be very thorough in your explanation since I am using your powerpoint to teach myself how to do these things
• final grades are due in 2 weeks!!
• this will take you some time so do NOT wait until the last minute to complete this
• this will be your only extra credit opportunity so don't squander it
• FINAL PPOWERPOINT PRESENTATION must be in my email by Saturday, 3/19/2011 at 12:00 pm
• have a safe and fun spring break!

You will have a diagram quiz on Monday, March 22, 2011 where you will utilize several theorems including:

1. vertical angles are ....
2. linear pairs are ....
3. the sum of all 3 angles of a triangle is ....
4. the sum of all the angles of a polygon is ....
5. if two parallel lines are cut by a tranversal, then .....

if you would like to practice what this would be like, there is a practice diagram on the Ch 4 and 6 pretest with solutions pdf on my website (page 3 of 5)
