<span><span>Corresponding angles are congruent (same measure)So in the figure above, the angle P=P',  Q=Q',  and R=R'.</span><span>Corresponding sides are all in the same proportionAbove, PQ is twice the length of P'Q'. Therefore, the other pairs of sides are also in that proportion. PR is twice P'R' and RQ is twice R'Q'.
