the distance formula is really pythagoras' theorem 

and you know 

c^2 = a^2 + b^2    is a right triangle

then 

c^2 < a^2 + b^2  is acute

c^2 > a^2 + b^2 is obtuse

it you want to classify triangles based in scalene, isosceles and equilateral 

you can use the distance formula to find the length of the sides, looking for equal lengths


the slope helps with right triangles 

if the slope of 2 segments multiply to -1, then the lines are perpendicular. 

so lots to know
