Can you make a triangle out of the following lengths: 8", 12" and 2.5"? explain
because 2.5^2+8^2doesn't equal 12^2
no, 12 is more than 8+2.5. for it to work, the longest side needs to be less than the other two sides added together and more than the difference between the other two sides. The other answer is only for right triangles.
