Spoiler for did we forget?What's triangle inequality?

Spoiler for possible trianglesSpoiler for the triangle inequality theorem

so triangles like 0,6,6 fail the triangle inequality theorem since 0+6 is not greater than 6

So, 0-angle triangles are being discriminated agianst. That's an injustice.

Still, my last post gives two different answers even for that case.

Spoiler for so which is it?

That depends on how "probability" was meant in the OP. The way OP was worded ("probability of forming"), it looks more like 4/10. In this context, I assume, we ** form** a triangle by randomly picking sides for it. If OP said: "What is the probability that the triangle

Past prime, actually.
