thank you so much, sir! this was very helpful and i understood very quickly. very helpful for my test tomorrow ;)

... 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 😊

[@mohanaram8301]

wonderful..explanation is so simple and easy to follow. Thank you so much🙏🙏

[@vincentxie3090]

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 well explained thanks!!!!

I love your work❤❤❤❤❤❤

[@msharyoretxmesh291]

You are the best teacher please explain about angels and lines and transversals please do it today if you can

[@RabbirraaDerese]

Wow good example

[@deseriearmstrong43]

Good job thanks sir😊❤👏👏👏

[@MathTeacherGon]

Most welcome

[@leendissi-5683]

good job

[@hhvlogs4885]

thanks you so much my concept was cleared in 5 minutes 😃😃

[@GeorgeLungu-ip7iz]

Perfect example ❤❤

[@user-no1lp3lv7x]

Perfect lecture👍👍👍👍👍👍👍

[@MathTeacherGon]

Many many thanks

[@taiwojaiyesimi6155]

Good

[@unity_king2010]

The 3rd one Is wrong your meant to take the 127 away from 180

[@latoya267]

Great letcher of angles I'm so bad at them at school 😂

Missing triangle

[@arjay2002ph]

formula:
x + y + z = 180
then just follow the method for solving the missing variable as trained
mathematics is just pure common sense IMO

[@solaiman1003]

Salmat, sir. Nakapasar na gyud ko♥️

[@MathTeacherGon]

welcome!

[@rakshitl783]

Sir is left handed

[@science-health-safetymusic2322]

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.

[@justinvelasquez2209]

Thank you Sir i can finally complete the assignment my teacher gave me

[@adeyola3241]

I don’t think this lesson is for jss1😢

[@danieladesola1552]

It is I'm in ss2

[@LordLorenceAlbores]

Bro come from Philippines

[@kayrizzz]

And he for sure knows more then you

[@sethjazziell5783]

at what grade po ito tinuturo ?

[@zindoriyam]

grade 8 po

[@Rayla-bn8xy]

I did it at grade 6

[@abrahamzira3096]

I really understand your teaching very well sell your accout I want to send you money
