I assume you want to know a permutation about how many ways they can be in the final set-up.
Order matters, which is why this is a permutation.
Formula: P(n, r) =
where the permutation is
, with P for permutation.
Plug in:
4!/(4-2)!
4!/2!
(1 x 2 x 3 x 4)/1 x 2
(3x4)/1
= 12
12 ways.
Answer:
I don’t think it’s a right triangle
Step-by-step explanation:
5^2 + 8^2 should equal 12^2 for it to be a right triangle.

The idea is to find a linear combination a_1(5, -6) + a_2(-2, -2) = (-6, 2)
It boils down to a system of equations:
Take the augmented matrix:
<span>[<span><span>5<span>−6</span></span><span><span>−2</span><span>−2</span></span><span><span>−6</span>2</span></span>]</span>
Reduced form:
<span>[<span><span>10</span><span>01</span><span><span>−<span>811</span></span><span>1311</span></span></span>]</span>
-(8/11)*(5, -6) + (13/11)*(-2, -2) = (-6, 2)
