Proving Triangles are Congruent - MathHelp.com - Math Help
For a complete lesson on proving triangles are congruent, go to www.MathHelp.com - 1000+ online math lessons featuring a personal math teacher inside every lesson! In this lesson, students learn the following postulates related to congruent triangles and triangle proofs. If the three sides of one triangle are congruent to the three sides of another triangle, then the triangles are congruent (Side-Side-Side or SSS). If two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the triangles are congruent (Side-Angle-Side or SAS). If two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the triangles are congruent (Angle-Side-Angle or ASA). Students are then asked to determine whether given triangles are congruent, and name the postulate that is used.

I appreciate your neat handwriting and symmetrical looking angles unlike any teacher I’ve had lol

You're right. I'm so bad at Math, I don't know if it's because I'm just really that dumb or if it's the teacher.
She rocks the way teachers explain it can be difficult at times but thank God for youtube education lol
Thanks lady for the well explained examples of these angles and references. wish you were my maths teacher when I was at School. again, much'ly appreciated it.
I'm so glad the Internet exists so that I can search this up.
thanks robot girl :)

Nice handwritting btw, it made me learn much more better. Your explanation is also by far awesome
understood very well
well-done video i remember proving triangles congruent in geometry lol.. i always thought that the SSA worked i was like "WHY DOESN'T SSA WORK!!" lol then someone drew two triangles with SSA but were not congruent then i was like "oh yea.." lol go SAS!!! that's the best postulate
It takes my teacher 1 hour to explain this and I still wont get it. Thank you internet.
why can't my crazy geometry teacher be like you?
I wish you were my teacher
Thank you this helped !
...I never learned Geometry. I'm in 9th grade and take Pre-calc...so right now I'm thankful for that.
I under stood this thanksmam
Math is cute by definition. She seems cute too, so she is the right person for this work. End of the proof. Incidentally, I'm gonna see all his videos!
Thanks it was really useful..
Thanks for the video, it really helped. :)
I understood this much better than my teacher, why don’t they teach kids like this
i was looking for different postulates..this stuff is all easy its jsut when you forget it...
i understood it so much clearer than the way my geometry teacher explained it ._.
thanks for this help
More help on Year 10 similar and congruent triangle Please!!!!!
Angle Side Side IS possible. As long as the triangles have a right angle, then it will be HL
yoooo ong u a real one fr🙏🙏💯
-.Thankyou! It's a great help for me!
Thanks for the last minute help
Iam only days old when this video is made, now im here to learn math😀
I was 27 days old when this came out lol not even a month old even if you count the shortest month
ASS does not hold since we may have diffrent triangle with same angle side side measurement
Awesome video!:)

can we consider the part D as Angle Side Side (ASS) ? can you post about the theorems ;)

Thanks!
AAA does not work because the side lengths can be differnent, however there is no problem with SSA
proving is important. we can use it in our daily lives!

Lol been trying to get my teacher to understand it must exist i mean ASA who wouldn't try as hard as they could to make that work lol.
It only works on a right triangle, and is therefore known as the HL postulate.
thank you
i could not understand the no d . please explain it here , or anyone else here to explain me why d is not congruent
where is the proof of the A-A-S theorem? i need it! where's the stuff for math majors? glad this is here for guys that need it though.
made it seem so easy..
And for d) can't it be HL if there is a right angle sign?
Nice hand writing:)

figure D: if SSA is congruent to SSA, wouldn't the unmarked sides have to be congrurent - making SSA a valid postulate?
..hmm but there is another posibility of congruency right? am not too sure but i think there's one that has hypotenuse in it..but am not sure
thanks :-)
Soooo they gave us this to review during the corona quarantine
My teacher always says "ASS doesn't work and AAA doesnt work" AAA as in the insurance company.
Only thing to say is I like her handwriting lol. And its pretty easy to understan.
You're an amazing teacher, like wow you taught me in 3 minutes!
@Kbanasko How'd the exam go?
@AngelRestivo because the 2 sides with only one line are congruent to each other, and the 2 sides with two lines are congruent to each other:)
She didn't give an example for the RHS type of congruency. In RHS axiom, there should be a right-angle, a hypotenuse and a side.
Just realized this was 12 years ago.... before online school for corona...😵🤧

why are there two lines on one side of the triangle and only one line on the other side of the triangle??
I don't know how u predict the next step I have tried tons of questions but I cant learn plz help b
wayching every math video on youtube ..finals tomorrow
In A, B, and C, the triangles are equal, but in D, the triangles are not necessarily equal.
thx

i didnt get what i was looking for. i wanted to figure out the side names and the angle names which she didnt mention. i guess everybody can figure out SSS and ASA
RHS is also used
Wow! But please add letters to the sides to easily identify...
