3.3 Proving Parallel Lines Project

Here is an example of a photo with parallel lines and a transversal outlined. I did it during lunch and it took about 10-15 minutes to put together. You can either write your paragraph on the photo or on the blog when you submit it.

Here are some steps that might help get you started:

1. Find a photo/picture. It needs to be where parallel lines are occurring in life. For example, in architecture, or nature. It did not take long for me to find photos I googled it.

2. Copy the photo to Paint. net (program is on your computer), and outline your parallel lines and transversal in bright colors so I can see it well. Then save it on your computer.

3. Upload the photo into picnik.com. Under the "create" tab click "text" and you can easily name your lines and angles. You can also type in your paragraph here explaining the use of your theorems proving the lines parallel, or you can do this on the blog when you submit it

4. Save the photo again and go to your blog. Make a new post and upload your photo. Make sure your paragraph is included either on your picture or on your blog. Then submit your project and I will grade it on your blog.

4 easy steps to having this summative grade complete. You can do it, just set a side an hour of your time.

2.5 Algebraic Proofs

We are starting 2.5 today. Use these videos that are linked to the page, as well as the 2.5 Reteach worksheet, to introduce yourselves to Algebraic Proofs and what they entail. The first video introduces lesson 2.5 and the second goes through two examples step-by-step so you know how to set up a proof and what they consist of. The 2.5 Reteach worksheet should get stapled into page 22 of your notebook.

Notice, that on your 2.5 Reteach worksheet the "symbols" and "examples" columns use conditional statements (if-then). We will go through more examples together as a class.

2.4: Biconditional Statements

PowerPoint and Notes

Go to Blackboard and watch the PowerPoint for 2.4: Biconditional Statements.
It is under class Information. Complete the notes handout that follow the PowerPoint. Watch the PowerPoint after you are done with your TEKS check or if you were absent the day we went over this lesson.



Gizmo

After you are done filling out the notes and watching the PowerPoint then start the Gizmo for Biconditional Statements.

1. Go to explorelearning.com
2. login, if you have never logged in before then make an accout (use your computer sign in for your username and password)
3. Have you enrolled in my class? If not, then here are the class codes for all my classes, so find your period and then use that class code to enroll:
1.LVUU43ZEY5
3.RBMYFYK8P4
4.NQDRCAN28Y
5.KFV3AK7SEZ
7.4ZJELAWM8S
8.6HNGL5Y2TL

4. Once you get logged-in and enrolled click on the "Biconditional Statements" Gizmo.
5. All the instructions you need are on the 2nd piece of paper in the handout for the PowerPoint. The directions tell you which tab to be on and which category to be in under the drop down menu, so read everything carefully.
