you'd have to know the slopes.

anonymous · Answer

you can't use the pythagoras formula. you only use that if you ALREADY KNOW that the triangle is right triangle.

anonymous · Answer

Problem assumes knowledge of the length of the sides from my reading. 

Like, is a triangle having sides 3, 6 , 4 a right triangle?

anonymous · Answer

No, I don't think so. I came to an interesting conclusion.

We know that for a right triangle with unequal sides, the ratio of each side will be 1:2:root(3). You might be able to test whether or not the sides of a triangle with measures 3:6:4 create a RIGHT triangle by comparing the known 1:2:root(3) ratio rule with the 3:6:4 postulate.

My attempt to prove the relationship between the two triangles didn't work. So I came to the conclusion that a triangle with sides 3:6:4 couldn't be a right triangle.
