Parallel Lines Cut by a Transversal & Angle Relationships!

On this lesson, you will learn everything there is to know about parallel lines cut by transversals and angle relationships including supplementary angles, complementary angles, vertical angles, alternate interior angles, alternate exterior angles, and corresponding angles.

This lesson answers the question: How do I find a missing angle? What are supplementary angles? What are complementary angles? What are vertical angles? How can I find vertical angles? How do I find alternate interior angles? How do I find corresponding angles?

Feels good to know other people are struggling alongside you.

4x+38+2x-18=180
6x+20=180
6x=160

**x=26.7**
substitute
4(26.7)+38=144.8
2(26.7)-18=35.4

then just arrange them based on the understanding of urs on the angle relations such as alternate and exterior angles as well as vertical

:D

Anyone else get this video for "homework"
I don't know why I put that there.

When online school makes you watch THIS

transversals and angles in general are the death of me

[alesiarolle]

I’m just like really really dumb cuz I can’t get nun right😭

corona got us watching videos anyone else?

Thank you so much! I’m on the last part of chapter 3 in class. However, I still struggled with 3.1, though I read and practiced problems in the book constantly. Then, I came across this and all of sudden, it’s smooth sailing! Better explanations then my teacher! The test I’m studying for is the last, math test of the year. It’s this Thursday. I can guarantee that I can at least do better than I usually do with this newfound understanding. I really want to give my all into this final for a strong finish! I learned in more in 9 minutes from you, than in a week, from my teacher!

Ive watched so many other people but couldnt understand it till i watched yours, you explained it so well

[kristapeterson]

Great lesson so impressed with these color coded math lessons. As a teacher, it's helped me in my own classroom with visual learners. I myself am very visual and this has been a great tool! Can you post the answer for your final question please?
Keep up the good work!

Bruh I'm gonna take a test on Monday with a teacher that just gives us notes and barely explains it. This helped so much, thank you🙏🙏

The bigger angle is 144 + 2/3 degrees and the smaller angle is 35 + 1/3 degrees

[ninaedwards]

The best explanation I've seen so far. I love the X O method. Thank you!

My geometry homework got me watching this! TYSM <3

[consciousbeautycb]

Omg, you saved me! Watching other videos, it just didn't come clear but after your video, I'm much more confident. Thank you

[gab]

man i need to watch this for a note book assignment and in the first 3 minutes i already finished WOW

[nuttybutty]

anybody watching this and still not getting it

[meherleengarcia]

Is there any way you can make a short video solving the problem you offer at the end of this one? I understand the entire concept and I looked at your answer as well...Unless I am doing something entirely wrong, I cannot figure out how to solve this last one.

Thanks so much! (I am teaching GED classes and the color graphics help immensely!) Keep up the good work! (and yes, NYC does have the best pizza!)

For the answer I got -28. This is what I did.

4x+38=2x-18
I subtracted 2 from both sides and got 2x+38=-18
Then I subtracted 38 from both sides and got 2x=-52
Finally, I divided it and got -28.
Do you think you can correct me on what I did wrong and explain to me why I did that?
Thanks. By the way, I think your videos are cool too. Your rotations and slope video really helped me a lot. To be honest, I am 13 too, so most likely I got this question wrong as well.
