One triangle on a graph has a vertical side of 3 and a horizontal side of 4. Another triangle on a graph has a vertical side of 9 and a horizontal side of 12.

Could the hypotenuses of these two triangles lie along the same line?

No, because they are not similar triangles

Yes, because they are similar triangles

Yes, because all triangles can fit along this line
