scalene... then you could test them using pythagoras' theorem to see if they form a right angle.

okay, but how did you figure that out..?

camper4834 · Answer

you do no math to say that the triangle is scalene

camper4834 · Answer

its scalene simply because those numbers you gave us for the sides... none of them are the same.... and thats what makes it scalene

camper4834 · Answer

if you said 19 12 12, we would automatically know that it is isosceles because two of those numbers are the same
