First of all, I don't know if this is the right sub-forum for this question. I never had the difference between geometry and trigonometry, so keep that in mind before flaming me.
Now my question;
If you know the length of the hypotenusa in a right triagle, and you know the something* of the two other sides, can you calculate what those lengths are? I think it is very possible. What if you only know the something** of the hypotenusa and the two sides?
*If AB = 4 and BC = 2, then the 'something' is 4:2, or 2:1.
**If AB = 4 and BC = 2, then the 'something' is sqrt(20):4:2, or sqrt(20):2:1.
And another thing, I've seen people use images of square roots and such, how do I use those too? And is there any good (and possibly free) maths software out the for geometry, parabolae and things like that? (I'm talking about 'visual' maths)
Thanks in advance for reading this, and another thank you to the people who will help me.
