Hello, 'nons. Beginning in January, I'll be an undergrad in Physics in a top 100 university. However, I suck at plane geometry and, if I don't change that, I won't be able to learn mechanics and calculus. I attempted to learn plane geometry 2 years ago and I did a little bit of progress, but I got to a certain point where it was so hard that I gave up and went to study other topics.Today I opened my geometry book again and resumed from where I stopped, but it's still hard. I read the theorems and their demonstrations but they don't click in my mind. I wonder if it's because I'm too stupid or if there's other reason. I was able to successfully learn elementary algebra on my own (I didn't learn in school because of the pandemic), as well as combinatorics and probability (hs level). Geometry is the only thing that seems impossible to me.How do I learn this shit?

>>16873531I don't think you need that much synthetic geometry for freshman physics, only some basic properties of angles and triangles. What else would you need? Everything is analytical geometry nowadays
>>16873531- Learn it in context of physics and calculus problems. As in just do problem books, and compare your attempt to the model solution. - Try idiot-proof books like AOPS Introduction to Geometry. - Leave 4chan.- You made a really bad decision to study physics. Not even in a good university. Especially in this economy. Check job portals website, type in "physics". Be realistic. Learn public speaking. Learn writing. Learn video editing skills. Learn teaching skills. Make friends with people with bright future. Study hard. This is such a retarded decision that most likely will ruin your life. No one care about "problem-solving" skills. Don't shitpost on 4chan any more. But you won't listen anyways. No one ever listens.
>>168736231. I am using a book that's popular in my country. It's high-school level, yet it is somewhat rigorous. I don't think finding a new book will make a difference, I just need to learn how to study geometry. I've never felt so much difficulty learning a topic. I found it easy to learn algebra, sequences, combinatorics, optics and calorimetry, but geometry has been hard. I need to know plane geometry for trig.; 2. I really just came to 4chan to post this, otherwise I barely use it;3. My university is tuition free. Can you imagine that, shitmerican?
>>16873644>I need to know plane geometry for trigVery little, really: >>16873612>I've never felt so much difficulty learning a topicMaybe you need to pick up on proof writing in general? Try "How to Prove It: A Structured Approach" or "Book of Proof">It's high-school level, yet it is somewhat rigorousTell me the name of your geometry book, no matter the languge

>>16874029But trigonometry is vol 3. Shouldn't you read this series in order? You were saying you wouldn't have any problem with volumes 1 to 8? Thinking you need plane geometry before trigonometry is not the right mindset, it would be better if you started mechanics right away and backtracked if needed, do you know what physics books they use at your top 100 university? Besides, your hue guide mentions the book by Morgado, Wagner and Jorge. Try that too
