Draw the image of figure ABC when translated by directed line segment u. Label the image of A as A', the image of B as B', and the image of C as C'.

Explain why the line containing  is parallel to the line containing .

There is a sequence of rigid transformations that takes A to A', B to B', and C to C'. The same sequence takes D to D'. Draw and label D':
