Thursday - 4/14

 

We started class with a review of last night's homework on Simplifying Radicals.  Next, we started the notes for Section 8.2, which covers the Pythagorean Theorem.  We looked at simple examples, as well as ones that include Isosceles Triangles and Trapezoids.

 

HW: Ws 8.2 #'s 1-4, 9, 10, 12, 15 and Ws "Practice 31" #'s 1-9 odd, 23, 24.

 

Notes:8.2 Notes

 

 

Friday - 4/15

 

Today we completed the notes for Section 8.2.  We practiced using the Pythagorean Theorem on a multitude of pictures.  Some pictures had Isosceles or Equilateral Triangles, while some had multiple Right Triangles where we had to use the Pythagorean Theorem two or three times to find the desired length.  We also worked on drawing our own pictures of Rectangles, Squares, and Rhombuses, only to use Right Triangles that resided within each shape.

 

HW: none

 

Notes: 8.2 Notes

 

 

Monday - 4/18

 

We started today by completing the notes for Section 8.3.  In this section we looked at the Converse of the Pythagorean Theorem.  We used this theorem, and others, to determine whether a triangle was acute, right, or obtuse.  After some practice we started the notes for Section 8.4, which covers Special Right Triangles.  Here we learned how to find missing sides of right triangles without the Pythagorean Theorem.

 

HW: Complete #'s 1-8 and 13-20 on ws 8.4.

 

Notes:8.3 Notes and 8.4 Notes

 

 

Tuesday - 4/19

 

After we reviewed last night's homework we spent some extra time practicing problems involving Special Right Triangles.  We looked at Equilateral Triangles and Squares and how they contain 30-60-90 and 45-45-90 triangles.  We also reviewed for tomorrow's quiz on Sections 8.2-8.4.

 

HW: You should complete the following problems as review for tomorrow's quiz:

 

Pg 291 #'s 5-7, 9, 10, 12-14, 16-18

Pg 292 #'s 14-20, 24, 26

Pg 296 #'s 1-6

Pg 301 #'s 1-6, 9

 

Notes: 8.4 Notes

 

 

Wednesday - 4/20

 

Today, we started class with our quiz on Sections 8.2-8.4.  After the quiz we completed a measuring activity that helped us understand the meaning of the Trig Ratios (Sine, Cosine, and Tangent). 

 

HW: Complete the Ratios Table from today's Right Triangle Activity   

 

Notes: none

 

 

Thursday - 4/21

 

We started off today by reviewing the results from yesterday's triangle activity.  After some calculating and conversation we learned about Sine, Cosine, and Tangent, and how they are simple directions that tell you to compare specific sides of right triangles.  Next, we practiced writing Trig Ratios when given right triangles.  Next, we learned to solve for missing sides of right triangles with Trig Ratios.  

 

HW: Complete #'s 1-8 of the Kuta worksheet you got at the end of class.

 

Notes: 8.5-8.6 Notes

 

 

Monday - 4/25

 

Today, we continued to work in Sections 8.5 and 8.6.  We used Inverse Trig Functions to find the measures of missing angles, and continued to use Trig Functions to find lengths.  

 

HW: Complete ws 8.5-8.6.

 

Notes: 8.5-8.6 Notes

 

 

Tuesday - 4/26

 

After reviewing last night's homework we finished up Sections 8.5 and 8.6 by looking at pictures of Overlapping Triangles.  We learned to use the two triangle separately to find information that will lead to the missing length.  We finished class with a review of all 3 ways to find missing sides of right triangles: Pythagorean Theorem, Special Right Triangles, and Trig Ratios.  

 

HW: Pg 323 #'s 5-16 and Pg 325 #'s 19-24.

 

Notes: 8.5 and 8.6 Notes

 

 

Wednesday - 4/27

 

Today we completed our work in Unit 7 (chapter 8).  We started and completed the notes for Section 8.7, where we learned to use Trig Ratios to help us sove Application problems.  

 

HW: Complete Pg 318 (WE's) #'s 1-8

 

Notes: 8.7 Notes

 

 

Thursday - 4/28

 

Today was review day for Unit 7.  We started by going over last night's homework on Applications of Trig Ratios.  Next, we looked at how different questions will look tomorrow and how we decide to use Pythagorean Theorem, Special Right Triangles, or Trig Ratios.  Finally, we got into groups and completed a graded groupwork in order to prepare for tomorrow.

 

HW:  Complete the Unit 7 (Ch 8) Review if you did not do so in class. Also, check out the following problems in the text for extra practice: Pg 320 #'s 1-5 and the Chapter Test on Pg 324-325 #'s 7-16.

 

Notes: none

 

 

Friday - 4/29

 

Today was test day for Unit 7 (Chapter 8).  After the test we started working on a practice assessment for Monday's Core.

 

HW: Complete the Practice Core Assessment.

 

Notes: none
