Couldn't the line in the square not be the diagonal, meaning we wouldn't know if it's dividing the square into right-angle triangles or not?

Hi Charlotte,
Although figures may not be drawn to scale, the relative position of geometric objects are what they appear to be.
So, if a point appears to be to one side of a line, then it is there. Or if a line appears to pass through the center of a circle, then it does.
Since line in the figure appears to pass through opposite vertices of the square, it does and therefore is a diagonal.
Note: If we were not told in Column A that the figure is a square, then we could not assume that it is based on the appearance of the figure -- it could be a rectangle. In this case, however, the diagonal would still be a diagonal.
