Fox 354

Roland Sampy has submitted this problem.
It looks right, but not confirmed yet.

Fox 353

Tony García‏ from Dominican Republic submitted this one.  It looks like it requires brute force.  Better than being idle I guess!  So enjoy...

The answer is not confirmed yet.

We will add comments later...
There are many lazy observations that could help.

Fox 351

Let's start with this simple one for high-schoolers :)
Pure-geometric solution will be appreciated.
We'll build upon this later.

Based on the evidence presented by Bleaug, this is updated as follows:

This is just one step forward to the general case. Should not be very hard unless the claim is wrong :)
Yes, a geometric solution will be appreciated...

Fox 348

We'll return back to Sampy's question later. But, for a change let's see a simple one - or at least it looks simple. We're looking for the shortest proof of the claim below. May be purely-geometric one? Or is the claim wrong? Let us know...

Fox 347

Below is the general case submitted by Roland Sampy.
There seems to be at least 2 expressions for r.
We had a solution, but it looked a little clumsy. Moreover, we lost it :)
So, do help us to recover... Oh yes, do enjoy as well...

Fox 346

Wooow... This has been quite long time, huh? Life makes people busy (although that is not the exact excuse.)

Is everybody alive? What have been up to? Bleaug? Newzad? Polar Fox ?? ...

The following fox is a simplified version submitted by Roland Sampy. We should be able to ask a general version later. You mean next year??? Who knows hopefully earlier. Here you are...
Oh, by the way the answer was not confirmed yet. So, the claim could be wrong.

A happy new year to everybody.
