A(2,3) B(-2,-3) C(-6,1)
now use distance formula and find the length of each side}
AB=sqrt%28%282-%28-2%29%29%5E2%2B%283-%28-3%29%29%5E2%29
AB=sqrt%28%282%2B2%29%5E2%2B%283%2B3%29%5E2%29
AB=sqrt%2816%2B36%29
AB=sqrt%2852%29
AB=7.2%7D%7D%0D%0A%0D%0A%0D%0A%7B%7B%7BAC=sqrt%28%282-%28-6%29%29%5E2%2B%283-1%29%5E2%29
AC=sqrt%28%282%2B6%29%5E2%2B2%5E2%29
AC=sqrt%2864%2B4%29
AC=sqrt%2868%29
AC=8.3%7D%7D%0D%0A%0D%0A%0D%0A%7B%7B%7BBC=sqrt%28%28-2-%28-6%29%29%5E2%2B%28-3-1%29%5E2%29
BC=sqrt%28%28-2%2B6%29%5E2%2B%28-4%29%5E2%29
BC=sqrt%284%5E2%2B%28-4%29%5E2%29
BC=sqrt%2816%2B16%29
BC=sqrt%2832%29
BC=5.7

all sides have different length, and if so a triangle is scalene
