<p>Hello All,</p>
<p>I'm trying to prove something that we know that is correct but can't find how to do it or any example to show how to solve it.</p>
<p>Any 2-coloring of the scope of equilateral triangle must create a monochromatic rectangular triangle (That all of its vertexes and in the same color and they are positioned on the scope of the original triangle).</p>
<p>This problem is connected to Ramsey theory.</p>
<p>Does anyone know how to prove it ?</p>
<p>Cheers,</p>
<p>Itamar</p>
