The triangle is scalene as their edges are not equal: ST=[tex] \sqrt{4 + 16} = \sqrt{20} [/tex] VT=[tex] \sqrt{9+1} = \sqrt{10} [/tex] SV=[tex] \sqrt{1+25}= \sqrt{26} [/tex] So the triangle can not be isosceles or equilateral. And calculating the slope of the edges notated with m we may observe that their multiply result it is not -1 as in the cases of the right triangle. m[tex] m_{1} = (5 -1 )*(3-1)=4*2=8 m_{2}=(0-1)*(4-1)=-1*3=-3[/tex]
