Question 1137038
A({{{2}}},{{{3}}})  B({{{-2}}},{{{-3}}})  C({{{-6}}},{{{1}}})

now use distance formula and find the length of each side}

{{{AB=sqrt((2-(-2))^2+(3-(-3))^2)}}}

{{{AB=sqrt((2+2)^2+(3+3)^2)}}}

{{{AB=sqrt(16+36)}}}

{{{AB=sqrt(52)}}}

{{{AB=7.2}}


{{{AC=sqrt((2-(-6))^2+(3-1)^2)}}}

{{{AC=sqrt((2+6)^2+2^2)}}}

{{{AC=sqrt(64+4)}}}

{{{AC=sqrt(68)}}}

{{{AC=8.3}}


{{{BC=sqrt((-2-(-6))^2+(-3-1)^2)}}}

{{{BC=sqrt((-2+6)^2+(-4)^2)}}}

{{{BC=sqrt(4^2+(-4)^2)}}}

{{{BC=sqrt(16+16)}}}

{{{BC=sqrt(32)}}}

{{{BC=5.7}}}


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