Fan&Medal for correct answer, please help me. This is the only one I don't understand and it's only because I am ahead of the classes and my teacher hasn't gone over this yet.
Two right triangles with the following dimensions are graphed with their hypotenuses on the same line:

triangle X:
horizontal leg measures 2 units
vertical leg measures 8 units

triangle Y:
horizontal leg measures 4.5 units
vertical leg measures 18 units

Which other triangles could also have their hypotenuse on the same line?

Answer choices will be below, I can't fit them!
