Two right triangles are graphed on a coordinate plane. One triangle has a vertical side of 3 and a horizontal side of 7. The other triangle has a vertical side of 9 and a horizontal side of 21.
Could the hypotenuses of these two triangles lie along the same line?
a) Yes, because they are both right triangles
b) Yes, because they are similar triangles
c) No, because they are not similar triangles
d) No, because one is larger than the other
