Consider two right triangles:
1. ΔABC with vertices A(0,0), B(0,2), C(6,0). Then AB is perpendicular to AC and AB=2 units (vertical leg), AC=6 units (horizontal leg).
2. ΔXYZ with vertices X(6,-10), Y(6,0), Z(36,-10). Then XY is perpendicular to XZ and XY=10 units (vrrtical leg), XZ=30 units (horizontal leg).
The equation of the line BC is

Check whether points Y and Z lie on this line:
Y(6,0):
- true;
Z(36,-10):
- true.
Answer: the hypotenuses of these two triangles could lie along the same line
