better than my math teacher.

Her voice is so monotone but all the yourteachermathhelp videos are so simple and to the point that it doesnt even matter

[TheMysweetypie]

THAT WAS A GREAT HELP! THANKS FOR POSTING THIS.. Im in my early highschool life and Geometry is already giving me so many problems. :)))

her voice is so boring

tnx for the help...God Bless

The triangles in part c) are NECESSARILY SIMILAR the moment she define angle M and T as an obtuse angle with a constant value (100 degrees). I don't understand why the lesson ignored trigonometry knowledge.  Perhaps they were just careless when they decide to put in a number.

the part b) is wrong. The proportionality should be demonstrated between corresponding sides which has not bee done in this video. The triangles in part b are not similar.

@SPBingo In a way, yourteachermathhelp is correct, so long as you find a common ratio for the sides, mathematically speaking, you can say that they are similar.

Well, thats what I thought anyways :) Usually if they have some sort of ratio between them, then nearly always, it will be the answer.

...Man. I am going into psychiatry (that doesn't look right lol) so I know I need alot of biology and basic math...but I am taking geometry to just be safe and I am continuing with math but wow! My math teacher can't explain this at all!!!!! She says the same thing every time....the sad thing is, I will never have to use this

I have a test on Developing proofs and all the Postulates and Theorems (SSS SAS AAS ASA) of Ch. 4 for Geometry coming up. Thank you for this so much and wish me luck!!

omg thanks so much for this vid, i have a test and the teacher didnt explain this! Thanks but if u know, what do u put for the reasoning when u say two proportions are equel?
