What is the length of a diagonal of a square with a side length of 8?

Ok, well a square is basically two triangles, right? the 45 degree right triangle. if you consider the rules for a 45 degree right triangle, you get: x, x, 2sqrt(x)

plugging in 8, you get the diagonal to be 2sqrt(8) or 4sqrt(2)

)because it's going in order of the math sign
