Thank you so much!!! I was literally having a mental breakdown because my teacher goes way to fast and it’s so hard to catch up. You’re a lifesaver.

I am a dutiful 9th grade homeschooler, and I find these videos very helpful. I just wanted to show my gratitude for helping me on the track to beat these silly tests that are forced upon me!

This video helped me to tell the difference between postulates, theorems, and proofs. I liked the way he explained that postulates are building blocks and theorems take them and prove they are true. A break down is postulates are statements assumed to be true, theorems are statements that have been proven, and proofs prove theorems true.

Bro this video was made 9 years ago on my BIRTHDAY!! Kind of ironic how I needed to use it nearly a decade after it was made. I'm in 9th Grade (I'm an Honors student), and this video was made when I was 6, now i'm 15!! Time flies by fast.

Thanks for this informational video, it very very much helped me on my test.

Love this. Small correction... squares do not have volume. Simply change word "square" to "cube."

Thank you so much Mr.Buffington, this was so helpful. I was able to finish my homework!!! 😀

Thank you so much for this video! I find it so hard to learn Geometry through Zoom meetings, and I have my first quiz tomorrow and this video cleared up so many of my questions!

[rembertob.marsadajr.]

Thank you, sir. I finally understand Mathematics and I really know what should I discuss to my classmate about proof of theorems. Other teaching just sucks!!

In high school we were taught that a line is the shortest distance between two points

This video was incredibly helpful for my virtual class!! Thank you

[Stareyiii]

The fact this was made when I was 1 years old and its helping me rn when im 14 in highschool in geometry 😭

[jaygiggle]

Thanks for the video! I've had a sub for nearly this whole unit; this helped a lot!

[hao-elpm]

Huh..its seems like its better for a school to just use youtube to teach students to save money than just hiring uselessness teachers(jk).😂😂😂

[joylynsinchiocotv]

This is so helpful.. Thanks for posting this video.

Im gonna fail the honors test tommorow. 9th grade 😁. Just started watching. Lets see what change

[swaglitchleaks]

I think you meant to say cube there, not square :) thanks anyway this was really helpful

[aayushmaan__subedi]

was that square?I think that should be cube.😊😊

[zombiestrange]

AB+BC!=AC, what I am trying to say is, you might have something like a curve. You should mention A, B and C are in the same line.

lol 4:30, better watch out the social justice warriors are coming
