Today’s Class – November 17th

Today we went over our homework from last week and learned a new theorem. And, as usual, were assigned more homework… ^^

To start off, we corrected the worksheet Inequalities of Sides and Angles of a Triangle, what involved some algebra. (By the way, don’t forget that, from now own, algebra will be very important– it will be worth at least 50% of the grade!)

After we finished correcting it, we went to the computer lab to work with Geogebra – this time with Theorem 5-12. However, we were not able to look at our Theorems’ paper before working in the computer.
The Geogebra activity involved analyzing the relation of the three sides of one triangle by using one inequality. After that, we had to solve three questions regarding that same theorem.

Theorem 5-12: (Triangle Inequality Theorem) If the addition of the lengths of any two sides is greater than the length of the third side, then a triangle is formed.
Hint: In this theorem, for a triangle to be formed the sum of every two sides must be greater than the third side; however, an easier way to find that out is by comparing the two smallest sides with the biggest side (small side + small side > biggest side).

And here is our homework for tomorrow: Page 270, # 14 – 30 (even) and # 32 – 40 (all).

Just a reminder: on this Friday we must show Miss Saatkamp at least one more acitivity of the Tangram Project done.

Well, I guess that's it! =)
