### Fox 214

Ajit Athle submitted this problem, as it neatly fits in our series on Equilateral Triangles. He said:
"Here's a simple problem to go in your current series on ET's. In equilateral triangle ABC, we've cevians BD (D on AC) & CE (E on AB) such that 2*BE = AE & 2*AD = DC. If CE & BD intersect in P, then prove, w/o using trigonometry or co-ordinate geometry, that AP is perpendicular to CE."
Thank you Ajit!

These ones are classified as "Drawing lines in the sand".
Beautiful geometric solution to Fox 208 by Pataki.
Won't be surprised if there are others!!!

### Fox 208 - Solution 1

### Fox 209

Where you stand defines who you are,
and emits traces of you to the sky.
Look at the brilliant stars in the night.
No! They aint no stars shining!
It is your eyes that declare the meaning of light.
Without your vision, all stars are dark.

There are things you ain't gonna erase...
Don't matter... even if you try hard...
Things that connect you to the farthest ends of the universe
Things that make you who you are.
A universe with a beating heart!
-- Dervish Fox

### Fox 208

This is a classic. You can find similar versions in several books.
Again should be solvable with no math, maybe with a little art - I guess.

### Fox 202

This kinda supports Red Fox' claim that every rational fraction is reachable
with simple unique configurations like the above one.
So one down {infinite minus one} to go!

### Fox 198

This is the beginning of a class of foxes with random processes.
The above process is a special form of a random walk on the plane.
We believe that this process is new! If you see something similar in literature, please let us know.
"Uniformly selected" means that every direction has an equal chance of being selected.
In other words: direction ~
Uniform[0, 360].
Point O is the origin. Generation of point A is irrelevant since OA does not change whether there will be a triangle or not at the end of the process.
Also, it is not important but assume that the random directions are generated clock wise.
The answer has not been confirmed yet, let us know if you find something very different.

The problem has been modified for the answer was not precise.
Let us know if you see a problem.
