Solution:
1. To find if a translation exists, the translation vector should be the same for both points.
2. Calculate the translation vector for pointsM N
- Translation vector:\vec{T_1} = (N_x - M_x, N_y - M_y) = (1 - 3, -4 + 5) = (-2, 1)
3. Calculate the translation vector for pointsK L
- Translation vector:\vec{T_2} = (L_x - K_x, L_y - K_y) = (-2 - 0, 1 - 0) = (-2, 1)
4. Compare the translation vectors:
-\vec{T_1} = (-2, 1)
-\vec{T_2} = (-2, 1)
5. Since\vec{T_1} = \vec{T_2}
6. Hence, the parallel translation exists and it is given by the vector(-2, 1)
