man, here i am 19 years old in college, and a week away from my statics and mecanics exam in CAD, with nothing but a simple understanding of the basic concepts, such like area and perimeter in geometry(i sucked at angles). I'm gonna binge watch a lot of your vids on geometry, hopefully try to understand most of it. Also, anyone out there slackin' right now, study early, you will probably need some of this stuff later if not now. And another thing, if there's someone out there, in the same position that i am, know that you ain't alone, and i wish you good luck 👍

MR. Organic Chemistry Tutor, thank you for an awesome video/lecture on Complementary and Supplementary Angles in Plane/Solid Geometry. These are the basic tools that all students need for a solid understanding of Plane/Solid Geometry.

that helped me very much even though its 3 years. ago. again thanks

[winnie-ej]

Thanks a lot sir🖤
U helped me for my test tommorow

[ismailseedat]

This has really helped even tho this was 4 years ago, Thanks you so so much

[corkythehippoman]

I’m watching this before a geometry exam and I’m suddenly much more confident, thank you

[deepikawinodani]

Thank you so much.... This lesson helped to me again and again thank you....

[Nerdysfit]

with the final problem. Its amazing how much information can be inferred from what seems to be a lost cause. I aim to be this analytical someday

[charlottereisse]

My teacher copied problems from this video 👍👍👍

[selfieswithapurpose]

well done you've taught me a lot that's why i'm gonna subscribe

[shawnkim]

Sir, I'm trying to follow what you're saying but I don't know where you're getting some of the numbers from you're not explaining.

[lourdesaceves]

OMG!!! because of this video i finally understand. THANK YOU!!!

[ava]

sir i think you may help me here thank you very much 😃😃

[catalinoperezantonio]

Good morning. I woud like to make you a questions. ¿What software are you use for mathematics?

[muazseid]

This is very very useful and very easy to understand. Thank you so much

[lorasampiano]

Complementary is 90° and supplementary is 180°

[ma-tanica]

this lessons are only about "do this and you get this". Just mechanical approach, no thinking at all

2:20 bro man says mins and seconds 😂 but overall excellent video

[llamablade]

You kind of sound like Zuko from ATLA. May i guess that you are somewhat filipino related?
Anyway, nice video. 👍
