I want to know what I can do with learning degree measure theorem, Thales theorem, Loci, Similarity, Congruence, etc?

The mathematics you're talking about is basic mathematics. You'll need to learn much more to be able to use it. It's like learning your alphabets. Be patient and one day you'll be illuminated.

Yeah...what he said.

For what it's worth, you're just now entering a world beyond your imagination: the wonderful world of mathematics.

Ok what do I do learning all the other geometry??

Buy a good book :) eg: www.amazon.com/www.amazon.co.uk/etc[/URL]..
Or just search the web :)

i have not read that book.

the value of concepts like congruence and similarity is that they identify properties that different shapes have in common. when this is noticed then other properties that these figures have in common can be derived. this saves work in understanding these shapes. i.e. something learned about one of them can be carried over to another.

similarity is especially useful. and proportionality. for example if you know that volume of similar figures increases as the cube of their sides, you can learn the volume of a large object by measuring the voilume of a small similar object and scaling up according to the cube of the increase in the side. i.e. if you make it three times longer it will become 27 times as voluminous.

so a man twice your height would perhaps be 8 times as heavy as you are.

this is a very powerful idea.

Ok. What are you people doing with all the geometry you have learnt??
