answer?
Dilatations.

Dilatations are the transformations of shapes by making them BIGGER or smaller.
The text book Glossary puts it in a more simple way. The transformation that changes the size of an object.
Out of all honesty *sounds like something Uyen would say* , I find this a teensy bit easier than Rotations. Because, unlike Rotations. This concept uses a Mapping rule.
and that mapping rule is . . .
( x, y) ▬▬▬► ( kx , ky )
"k" being that SCALE factor
simply put the number of time you multiply the x & y coordinates by to get (x , y) Primed

Let's say we have
[ ▲xyz ]
and the coordinates for the triangle were
[x] = (-2 , 8)
[y] = ( 6 , 2)
[z] = ( 4, -2)
and the scale factor is " 2 " or we want it TWICE as BIG
we multiply the X & Y by 2. so the coordinates for [ ▲xyz '] is . . .
[x'] = (-4 , 16)
[y'] = (12 , 4)
[z'] = ( 8 , -4)

try it on a grid . . .
[ ▲xyz ] is twice the size of [ ▲xyz ']

well, that's it for me. i gotta finish my map of atlantis. TAKE CARE ALL!!
KEEP IT RAWKING!

I miss you jellybeans :(

Well, I will put it in writing...being sick sucks.

I am happy to hear that everyone is cooperating with the subs and finishing their work. It sounds like Mr. Tram will definitely be the next sub I call if I have to be away. I'm glad to hear that Jason has officially deamed Eric as smart. I knew that all along...that's why he frustrates me so much. I am very lucky to teach such a bright jellybean jar. I know that everyone of you is capable of amazing things when you put forth your best effort.

See you on Monday,
Ms. A

Something big is happening soon

Something big is happening soon and you can be a part of DMCI history. Don't let anyone know, but I'll give you a clue. It starts on March 14, 2006 (a very special historic day). Follow the link to get another clue.

Good luck my jellybean mathematicians.

Today's class - Review for EXAM

Today in class we had a substitute for Ms.Armstrong and it was Mr.Orstrander. He gave us a piece of sheet that showed us on how to review or study for the EXAM on FRIDAY. And 4 or 5 students read each point out loud. When that was done, he handed us a Mid-term Review Math Exam. We went in groups of 3 or 4 and worked on it. And that was mostly it we did in class...im pretty sure...but if not just leave a comment and yeah...=D
