... Good day to you, Regarding the " Exterior Angle Theorem " it would be beneficial for beginning students to give a bit more explanation for a thorough understanding, because my experience with for instance tutoring students they will not remember the theorem without a clear understanding, so what I would do is to also first show the relationship between the exterior angle X and the interior angles ( T deg. , 88 deg. , 39 deg. ) of the triangle as follows ... [ assume unknown angle T ] .... 180 deg. - X deg. = T deg. = 180 deg. - (88 deg. + 39 deg.) ... - X deg. = - (88 deg. + 39 deg.) ... X deg. = 88 deg. + 39 deg. = 127 deg. ... now students can see for themselves that this theorem didn't randomly fall out of the sky! I personally don't like to learn theorems, but rather understand them! Thanks for your math efforts ... best regards, Jan-W
Great lecture on Angles 😊
The 3rd one Is wrong your meant to take the 127 away from 180
thank you so much, sir! this was very helpful and i understood very quickly. very helpful for my test tomorrow ;)
Very well explained thanks!!!!
wonderful..explanation is so simple and easy to follow. Thank you so much🙏🙏
Good job 😮❤
thank you so much this was very helpful
Wow good example
good job
Thank you sir really appreciated 🙏 👍 👏
Tank you Mr😊
I love your work❤❤❤❤❤❤
Thank you Sir
thanks you so much my concept was cleared in 5 minutes 😃😃
Whenever I worked out the missing number for each angle, what I did was I added up the sum of each triangle using my calculators and then subtracting the given number from 180° to figure out the missing number
Very useful explanation, keep it up sir
Thank you!
Good job thanks sir😊❤👏👏👏
Most welcome
Great letcher of angles I'm so bad at them at school 😂
You are the best teacher please explain about angels and lines and transversals please do it today if you can
Thank you!
Perfect lecture👍👍👍👍👍👍👍
Many many thanks
Good
Missing triangle
Perfect example ❤❤
Wow
formula:
x + y + z = 180
then just follow the method for solving the missing variable as trained
mathematics is just pure common sense IMO
Sir is left handed
your solution in triangle number 3 is wrong = x + y = 180, let y is our third interior angle; y + 88 + 39 = 180 = y=53, therefore; x + 53 = 180; x = 127..THE SUM OF TWO INTERIOR ANGLES (88 & 39" CANNOT BE ADDED WITH AN EXTERIOR ANGLE X DIRECTLY.
Salmat, sir. Nakapasar na gyud ko♥️
welcome!
I don’t think this lesson is for jss1😢
It is I'm in ss2
Thank you Sir i can finally complete the assignment my teacher gave me
Bro come from Philippines
And he for sure knows more then you
at what grade po ito tinuturo ?
grade 8 po
I did it at grade 6
I really understand your teaching very well sell your accout I want to send you money
So not diggre my Angeles
