Class Summary

Well, this is what happened yesterday,

Firstly, sorry for forgetting to post things yesterday, but here it is (my first post!!!). Well, anyways, yesterday we began our class with Mrs. Saatkamp giving us back our quizzes, and even though most people went really well, there was a little bit of confusion in question #2. The problem is that even though the two given numbers equaled up to equal ratios, we didn't have enough information to prove the triangles were similar. People, remember, FORGET looking for equal ratios because they won't always lead you to a correct answer, what everybody should always keep in mind are the theorems of this chapter, because even though we're not doing any provings, you SHOULD know them to understand the content and if you wanna go well on tests and quizzes, you better start studying the theorems and postulates because they practically summarize the content within a simple sentence. Well, I guess there weren't any other major problems with the quiz, most of the problems people had were different from one person to another, meaning that not everybody had the same problems. Well, after Mrs. Saatkamp collected our quizzes she reminded us of the announcements that were made in the blog, that the due date was extended (still to be defined), that we will have some more time in class to work on it, and most importantly, this will be the only project of the quarter (hurray!). For there not to be any complications with GeoGebra, Mrs. Saatkamp then showed us some useful tools that we could use in it. Well, before I explain what was said about GeoGebra, remember that before you put any information, define what scale you will use, and remember, the scale does need to fit on an A4 paper, so don't do something like 1 to 5 'cause it won't fit. Well, moving on, on GeoGebra, you can easily define the squares to be .25 or .5 big (although the units will always be one), all you have to do is:

1) Right click on the coordinate plane, and go to PROPERTIES
2) Click on GRID
3) Enable the option GRID (you can change the grid's color if you'd like, but really, it's totally not useful).
4)Enable the option DISTANCE
5)By clicking on the white boxes next to X and Y, just define what distance you want your grid to have from one box to another [if you're using decimals, use "." (period), not "," (comma), otherwise, it won't work].

Once you've got that settled, you can move on to graphing our beautiful math class into GeoGebra (=DD). To draw a line, something that could for example, represent a wall, follow these simple steps:

1)Click on the third box at the top coming from the left to the right, you should see a line, with a small segment between two points.
2) Hold down the small upside down triangle, on the bottom right corner of the little square.
3) Select the option Segment with given length from point
4) Click on the place in the coordinate plane where you want your segment to start.
5) Define what length (according to you pre-defined scale) your segment will have.
6) Press "enter" and you've got your segment, to make it go up, click on the point where it ends (the one that you didn't click in the beginning) and guide it up.

If you want to be 100% sure that all of your walls form 90 degrees perfectly, follow these simple steps:

1) Click on the fourth square from the right to the left, where there is a drawing of an angle named "A" (if you don't see this drawing, select the option Angle).
2) Click on the two segments that form your angle or the three vertices that for your angle.
3) An angle should appear, but if it's an reflexive (exterior, outside) angle, right click on the angle, select properties, and deselect the option Allow reflex angle.

Now, if you want to create a segment on top of an existing segment, such as to draw the board or a window, these are the steps you should follow:

1) Click on the same place you did to create the first segment, the third square from the left to the right.
2) This time, select the option Segment between two points.
3)Click on where you want this segment to be, and then drag it to where it should end.
4) If you right click it and go to style, you can make it thicker, to differentiate it from the other segment.

But remember, for the steps listed on top, you can also change step 2 to Segment with given length from point, as before, to make the correct length, by selecting Segment between two points, you are the one drawing the segment, meaning that you can easily get it wrong. Well, I guess that was all, after that, we all went back to our desks and the bell rang. I guess there are no major announcements to make, just for the lazy people who still haven't downloaded GeoGebra at home, DO IT, its quick and free, and you'll need it. Today we had the test, I hope everyone went well, and I am totally sure that tomorrow we will spend a lot of time discussing the last question of the test, and no Javier, I can almost assure you that it was NOT 80 (¬¬). Well, announcements about other classes, people don't forget that tomorrow we have a science AND history test (Oh no!!).

See ya'll tomorrow
