6. Composite Special Right Triangles

1/14, practice day


Hello guys!  This session is a practice day.  If you missed out, you must come see me for make-up work!

No homework.

5. Special Right Triangles

1/13, Textbook Chapter 8-3 starting on page 448

Today we look at the special patterns found in two kinds of right triangles.  It's all about solving for side lengths of a triangle without using any calculator.  How easy that would be!

Here's a website I found to explain it:
http://www.onlinemathlearning.com/special-right-triangles.html  (this one has a few videos that's good too)

Here's a couple of youtube videos I found to explain it:

Here's a website you can use to practice more:

Classwork:  handout provided.  If you don't have it, pick one up tomorrow!

Remember that your classwork is 50% of your daily grade.  Don't miss out!

4. Pythagorean Theorem and its converse practice

This is a practice day.  If you missed this session, please come see me for make up work.

No homework.

3. Converse of the Pythagorean Theorem

On Jan 9th, we learned about the converse of the Pythagorean Theorem, which are the Pythgorean triples.  It is still in your textbook chapter 8-2.  Look closely at example 4 in page 443.

Here's a website I found to explain it:

http://www.mathsisfun.com/pythagorean_triples.html

Basically, you are looking at three numbers like these:  3, 5, 4
And ask this question:  Can these three numbers form a right triangle?
You then plug it into the Pythagorean theorem formula, choosing the biggest number as "c"
Your answer will be a yes or no.


Here's a youtube video I found as well to explain it:

Classwork: page 444 #19-27,  #16, 18 are extra credit

2. Pythagorean Theorem

On Jan 8th, we worked on the concept of Pythagorean Theorem.  It is in your textbook chapter 8-2 starting in page 440.

As a review on what it's about and how to work the problems out, see the examples in the textbook.  Also, here's a link to great website that explains it as well.

Here's a video that someone made as well in youtube:
