not obvious geometry questions I struggle in finding solution for difficult geometry questions. By difficult though, I do not mean they contain advanced concepts, but rather simple questions where the solution is not obvious. The greatest challenge for me is recognition, not knowledge or technique.
I would appreciate any recomendations to websites, books or any other resources that will help me to develop this skill. In particular, I only find geometry questions to be a problem so questions on that would be the most useful.
Thanks in advance
-in response to question-

Recently this question came up in a test: Given the three circles are identical, all with a radius of 24mm and their circumferences touch the edge of the rectangle, calculate the area of the rectangle. Although I now know how to solve this question I could not find a solution in the exam.
 A: Connect the centers of the circles: you will get an equilateral triangle with side length $48\,mm$, hence height $24\sqrt{3}\,mm$. Project the previous centers on the sides of the rectangle: it will be clear what the side lengths of the rectangle are, i.e. $96\,mm$ and $24(2+\sqrt{3})\,mm$. The area of the rectangle is so $\approx 86\,cm^2$.
A: Just look horizontal and vertical lengths and dimensions. Vertically there is equilateral triangle height.
d= 48
$$ width= 2d,\, height = d+ \frac{\sqrt3 d}{2}, Area = d^2(\sqrt3 +2) $$
Plug in $d$ value.
A: Okay I think I got the gist of what you're needing here. You are looking for information on the application of the geometric theorems you are learning. Most of these should be algebraic in nature.
The problem is, like most questions that are algebraic in nature, there are multiple ways to find the solution, and the key issue is never the answer but how you arrive at it.
Most of this can intuitively come by via practice. Even though it can be long and arduous, it does work. 
Another way to deal with this is to question how the theorems work with each other. This would be like making your own problems and then finding a solution to them. It will be more work, but it will help you gain a better understanding.
As for resources, If you are using a book for studying this, then I definitely suggest using it. There are also websites like this that can help you with finding a solution. I would also suggest talking with a professor/teacher, as they will be able to help with the more difficult ones in a more one on one setting. They are experts at that thing, its what they do.
Finally if you are having test anxiety, the problem above kinda suggests that, then I definitely suggest talking to someone about it. It can be a extremely debilitating issue if not dealt with. Just keep in mind a test doesn't necessarily test a persons expertise in the subject matter, it only tests the capabilities of the person who made the test.
