MR. Organic Chemistry Tutor, thank you for another well explained video/lecture on Inscribed Polygons, Circumscribed Polygons and Circles in Solid Geometry. There is a pattern when solving these types of problems in Geometry from start to finish.
In the last problem, use the property : sum of opposite sides of a quadrilateral are equal if a circle is inscribing it. ∴ (AB + DC) = (AD + BC) ⇒ 14 + 18 = 12 + x --------> gives x = 20
En 8:00... ejemplo 2, si aplicamos el Teorema de Pitot, tenemos AB+DC=AD+BC. Si AB+DC=14+18=32, entonces AD+BC también suman 32; por tanto, 32+32=64. Ese es el perímetro. (At 8:00... example 2, if we apply Pitot's Theorem, we have AB+DC=AD+BC. If AB+DC=14+18=32, then AD+BC also add up to 32; therefore, 32+32=64. That's the perimeter)
on the last question the answer is 44+4sqrt(10) , because if you drop the altitude of the trapezoid you get the altitude to be 12. using the pythagorean theorem you get 12^2 + 4^2 = BC^2, 160=BC^2, BC= 4sqrt(10). find perimeter and you get 44+4sqrt(10)
You made a mistake on the video A trapeze as you described cannot have a circle inscribed that would touch all four sides The length of bc is 4^2+12^2=bc^2 BC=√160

I hate geometry but this guy makes it bearable
Hey
Thank You
For
Every video.
I like you. Somehow we need more people like you in our country.
i need to do binge watch of all his math videos just to understand the whole quarter of math subj bcs i didn't learn so well...ty so much
No matter what topic of mathematics i search , this channel videos always appear on top 🔥🔥🔥
Thats true
And not only mathematics!
I’m here because I have a geometry test and my teacher never taught us this
Lol you too
@@yeshuh7457 me too😕

Sameeeee

Wondering why AD is also 12. Any theorem to follow here?
math
@@thomasliu4545 Wondering too.
if
AB+DC=AD+BC
then why not the perimeter equal to twice AB+DC which is 64
it is absolutely helpful i have test tomorrow and you saved my life
How’d u do

9:05 two tangent theorem - two tangent start from one exterior point.
x and y their summation x+y=14
when i realized he explain so well
5:30 is this bell 🔔 I think he recorded this video in the last period however thanks for doing 3asy😂😂
thanks for the next day and time ⌚ ⌚

This video is helpful...hope you upload more...thanks
Very good video
You made a mistake on the video
A trapeze as you described cannot have a circle inscribed that would touch all four sides
The length of bc is 4^2+12^2=bc^2
BC=√160
I was going to comment this as well we or he may be missing something
AD can only be 12 if Angle A and Angle B are right angles, I missed that part if it is mentioned anywhere
Iam here because my mom wanted me to study this ;-;
Could the last problem be solved using the Pythagorean theorem?
idk but the answers are not the same
The only thing that I can bear and even exceed people's expectations is algebra. But geometry? Nah man I'm cooked
When you have to watch yt videos because your teacher never taught you this.
mood literally me rn
this is a great idea 💡 💡 🥞🌯🫔🍕🍟🌭🥪🌯🫔🥙🧆🍳🥘

Matt all dayyyy
u r the best
Thank you
ur my hero

i have a love hate relationship with geometry
I hate Math
I thought Geometry was easy until I saw this.....
same bro
gimme HIGH5
Spend more time for studying maths. Once you start loving maths then you can't ever hate it. Maths is a beautiful subject.😊
@@jessie9071 how can u say that? Math is the worst
How come your math is different than what I am thaught in Poland😅😭
Anyway thank you
goated
I hate geometry. This is the worst thing ever.
eh its fine, until i get hard one lmao
The only reasonable response to geomerty

HAJAJSJS I FORGOT ABOUT THIS
hello
I am hating my life because of this and btw our math teacher never taught us this thing😢😢😢😢😢
And I don’t think this is helping me! And I have final exams btw😙
