Hey. I've always wanted to learn geometry by myself, but don't really know where to start. Somebody mind helping me out a bit? Books, websites, anything.

Thanks

Hi Otsdarva;

Do you have any questions that you would like to post? You know a geometry problem.

hi Otsdarva,

Start at http://www.mathsisfun.com/geometry/index.html

Then post to the help page when you get stuck.

Welcome to the forum!

I just want to start geometry from the ground up, if you catch my drift.

Thanks bob bundy

Hi;

Have a look here to give you some background.

Thanks bobbym. Where do I go from there once I have the basics down?

Hi Otsdarva;

I cannot answer that for you. Once you start to progress a little post your questions here and I will try to help. Or someone else will. Once you show what you understand it will be easier to recommend something.

Thanks, I'll keep that in mind. One of the problems I have is with proofs, though. Hard as hell for me.

Hi Otsdarva;

They do not get any easier. The better you get at them only makes you work on harder ones, so you will always be stumped. Keep persisting!

hi Otsdarva

Geometry proofs.

(i) Make a good diagram.

Take care you don't make it so it is a special case ( eg. make an angle look like 90 when it need not be)

(ii) Say what you are proving and what you are given.

(iii) When you take a step in the 'proof', state, in brackets, why it is true. (eg. angle sum of triangle = 180)

(iv) When you reach the end, shout 'Eureka!' and write **QED** in big bold letters.

Or (iv) Post the problem, and how far you have got, to 'Help Me !' because some of us enjoy trying to help.

Late reply but after studying what was on your site I bought a Cliffs Geometry QuickReview book. Indeed my interest has kicked in once again and I'm starting to build a Geometry mindset.

Good luck! Hope it inspires you to love math.

Thanks bobbym and just recently I recovered a lot of focus I was missing before. I'm proud to be able to understand most of secondary school geometry and soon I will move on to the advanced.

Hi Otsdarva;

I recovered a lot of focus I was missing before.

Sounds like you are pumping up some neurons. But there is a danger, the brain only has a finite capacity. If you stuff too much geometry in their you could replace vital information.

That happened to me, I woke one day and could not even remember how many kids Brad and Angelina have. Or which NBA player has been arrested the most times or how to spell Rihanna. I broke out in a cold sweat and after many months of therapy they managed to put that vital information back in there. So write all that stuff down now.

Of course that result can be rigorously obtained, but who cares?

Hi Otsdarva;

All kidding aside, that is a fundamental point. Do not trust your memory, even if it is great. Write your thoughts down when doing math. Keep good, readable notes!
