Sir, you wouldn't believe how much you've helped me. I was getting ready to pull my hair out because of geometry. I spent many nights just looking at one problem and not being able to solve it. I was on the verge of giving up on it because it was that frustrating. Thank you so much for posting this video
I was also having same problems like you till 8th class but after watching this video and with my tution teacher guidance I am master at geometry and I love geometry more than algebra.
I am struggling with proofs. I'm in 8th grade and I normally get good grades but my geometry grade has been suffering all because of proofs. This video has done worlds for me. I have a quiz tomorrow and I feel prepared. Thank you🙏
I squeaked by Geometry in HS with a C-, in college went through Algebras Trigonometry Real Analysis ,a slew Calculus's w Analytical Geometry, Stats and Probability no problem. Now I'm almost 60 after a career in Industrial Maintenance/Electro-Mechanical Tech. I've always felt a big hole in my maths because of my ignorance of and inability to tackle basic geometry that required any kind of rigor or original on the spot analysis. I look forward to being a Maker in retirement and am thinking its time to get serious about plane and solid geometry. I dug out my old Drafting /Mechanical drawing kit and High School Geometry Text yeah I still have it and my goal is to complete every damn proof in the book no cheating. This video is the first time, that I can remember at least, that I was presented with a skeleton of the methodology involved in a formal proof. I must have missed that class or my attention was elsewhere at the time.
How did you get through analytical geometry and real analysis without a proof foundation? That sounds like it had to have been absurdly difficult without a mastery of the basics!
Given: Bird = word Prove: Robin = word Statement: Robin = Bird Reason: Bird property of equality Statement: Robin = bird and bird = word Reason: transitive property Robin = Word
Who doesn't! I swear all of the students in my class does ... like ... I am in grade 8 , BUT IDK HOW TO STUDY GEOMETRY .. like term one was pretty easy then... this annoying prove thingy came ... can someone tell me some tips on how to study the statement and reasons please??!
I am junior this year (2020-2021) and this is the worst thing I could possibly learn. Also, hello A.R.M.Y! I see a ton of you guys on like, every video i watch 😂💜 보라해
I’m taking my geometry final on Friday since they put me in precalc cause I knew everything about geometry. But proofs are my bad area, and I hope this will do me good
This was a neat flashback to my high school math days. I well remember doing proofs in Geometry and my Math teacher was tough on them. I studied hard for these and I remember one or two of his exams were all proofs. Had to memorize all the theorems, postulates, definitions, etc. One student loved proofs and always aced the exam. Thanks!
Thank you so much for posting this video! Proofs always confused me but your video helped me get a better understanding! I have the Geometry FSA tomorrow and I'll be sure to remember your 5 tips when solving a proof ^.^
Dang this helped me a lot!!...even though I already know the postulates,theorems,definition and properties...but I don't know the rules..so this helped me in my progress in learning
I’m fed up with mathematics, why can’t I just graduate already? It’s not hard to believe knowing that all teachers are the kind of people who are excessive or rather extra when explaining something so simple like a freaking proof! I’ve been looking up what a proof was for a while and then I have wasted a few hours trying to find a simple explanatory video that explains proofs exclusively, only to find this video which gave me more then simple! So thank you for actually giving me the tips and tools need to prepare myself for a test I’ve got on Monday! I haven’t slept yet and it’s already the next day!! So goodnight...or rather good morning!
Hi sir my name is shane and I am in 10th grade i am having a hard time with this and my teacher has not went over the proofs,theorems or anything among the matter I was wondering if you could send me a copy if you still have it?
May I ask? I don’t want to offend people who truly loves geometry. But is Geometry is just a set of rules that you must follow? I really love math, especially arithmethic. But I really am bad at geometry actually. Because this video stated that we must know all the theorems, postulates, and definition. Do we really need to know all the rules? I think geometry is actually nice, but I just can’t process it well. For me it just doesn’t make sense. I try reading Euclidean Geometry Book but all I see is a bunch of statements. If u have a nice book, please recommend it. I am not learning 4 school, so it can be any books. And again, i am sorry if this offends anyone. I believe geometry can be fun, maybe I process it wrongly. Thanks! (Sorry 4 my english btw)
Another tip is to, ignore where you're going. So what I like to do whenever im trying to prove is I like to get a separate sheet of paper and redraw the proof, rewrite the given, but ignore what I'm trying to prove, then from what is given I try and prove everything I CAN prove, just by looking at the given and examining the drawing. Then once I've proven everything I can, I then look at what I needed to prove in the first place.
i know no one is gonna see this comment but,,,I HAD A MATH TEST DUE YESTERDAY AND I AM DESPERATELY TRYING TO FINISH IT TODAY. JUST GIVE ME ONE TIME I WILL EVER USE PROOFS IN THE FUTURE.
Proofs would be so much easier if they allowed us to use a book full of the definitions, but no they make us memorize like what, 30 different theorems, postulates, and definitons
That was amazing! If you really understand all of the steps then surely you will do at least a level higher than before watching this video! If you keep on practicing you'll surely reach success!👍
Hi sir..May I ask for your own compiled list of theorems, postulates, properties, etc..? The one u mentioned that you give to your students at 1:21-1:27
ty for the video, rn im trying to prover properties of saccheri quadrilaterals in neutral geometry and am kinda stuck. I'm like 3/4 of the way there I just need a way to show that its altitude goes through the intersection of the diagonals then I'm basically done (I've already shown like 9 different congruences in the thing, just need 1 more step basically). Oh yeah and I'm a senior undergrad this year btw.
Suffering freshman here, I just never understand how these ever work, I’m cryingggg I’ve watched billions of vids by now just to understand this damn unit

Mary, I do have it but the postulate and theorem numbers will only correspond with the BJU geometry course. You can still use though. It's a PDF file so let me know where to send it. Rick
If u still have access to the reference sheet (from the beginning) can you email that to me or do a video on it. I will provide my email if u respond to my comment. Nvm i have found your email, and have contacted you.
Showing that the angles are equal (AAA) will only prove that the triangles TOB and SOA are similar. You need some info about the sides to prove they are congruent (which is the whole point of the question), and this is provided by the 'O is the midpoint of AB' given.
Not really. The HL postulate is a special version of SSA, which normally is not a valid postulate to prove congruence, except in the case where the angle is 90°
I’m a sophomore and I was absent when they study the postulate, theorems, definitions and properties can we’re having a test soon and I don’t know them. Can you send me that ?
proofs frustrate me even more because i just know after high school im literally never gonna use them again
It's not the actual proof but the process of logical thinking that you will use for the rest of your life - this is what we want you to learn.

Why couldn't you just prove the vertically opposite angle has to be the same, therefore the angles are equal. Skipping the whole congruent part.
Showing that the angles are equal (AAA) will only prove that the triangles TOB and SOA are similar.
You need some info about the sides to prove they are congruent (which is the whole point of the question), and this is provided by the 'O is the midpoint of AB' given.
AAS congruence and HL congruence are the same thing right?
Not really.
The HL postulate is a special version of SSA, which normally is not a valid postulate to prove congruence, except in the case where the angle is 90°
