Chapter 7

Today we are starting Chapter 7 - Similar Triangles and More. Below is the jargon for the chapter.

   

Day Two of Review for Chapter 5

Today in class, we continued are discussion about Chapter 5. On the test there will be questions about perpendicular bisectors (circumcenter), angle bisectors (incenter), altitudes (orthocenter), medians, midsegments, triangle inequalities, and vocabulary.

For the past two days, we had to answer questions like: (copy and paste the link through Google to see)

Let's Continue the Chapter 5 Review

Today, let us review perpendicular bisectors, altitudes, angle bisectors, and medians. For the test you should know how to draw and label each one them.




Here is a video on a perpendicular bisector.


Here is a video on a the median of a triangle.


Here is a video on the altitude of a triangle.


Here is a video on the angle bisector of a triangle.

Chapter 5 Mid Review

So last week, we had 9 jargon words to summarize Chapter 5. They are altitude, median, perpendicular, bisector, inequality, comparison,circumcenter, incenter, and orthocenter.  Below are pictures from class of the work we did in making our graphic organizers.

Last week, we also practice making the orthocenter - intersection of 3 altitudes, the circumcenter - intersection of 3 perpendicular bisectors, and the incenter - interesection of 3 angle bisectors on a website called Geogebra.

Go to www.geogebra.org, through Google Chrome to practice.

Mid Term Review

January  13 thru 17 is the BIG PUSH! We will be review chapters 1 thru 4:
Monday Ch 1, Tuesday Ch 2, Wednesday Ch 3, and Thursday and Friday Ch 4.
I will be posting review notes and sample problems for each chapter, on its particular day.
Study hard, the big push is on!

Today in Class ... Isosceles Triangle Review from Chapter 4

We wrapped up our understanding of SSS, SAS, ASA, and AAS. This is all apart of CPCTC - Corresponding Parts of Congruent Triangles are Congruent.

We also reviewed Isosceles Triangles. There are three important facts about Isosceles Triangles:
1) Two sides are always congruent, 2) Two base angles are always congruent, and 3) All of the angles inside of a triangle add up to 180 degrees. A pair or trio of students were assigned a story problem to work on.

Here are the problems. May you solve them?

During class on Monday, we will video tape a student solving some of the problems for extra credit.

Today in Class....Geometry!

We are talking about Corresponding Parts of Congruent Triangles are Congruent (CPCTC). This is chapter 4 section 3 of the book we are using. Go to www.flippedhighschool.com to see a video on the study guide of 4.3 in Geometry to review. Keep in mind that there are seven true statements about congruent triangles: 1) the statement of the two triangles being congruent (keep in mind the order is important), 2) there are three statements about the sides of the triangles, and 3) there are three statements about the angles of the triangles.

Here is a video about CPCTC:


Here is a nice video made for extra credit on CPCTC:


The chapter that we are in is about ASA, SSS, and  SAS.
