We are given that lines A and c intersect at point cap s Translate line A down line c until point cap s reaches point cap q Call the new line through cap q line b Because translations preserve orientation, lines A and b are ________. Because translations preserve angle measure, angle RSU is congruent to angle RQU prime For the same reason, angle RST is congruent to angle RQT prime , angle PSU is congruent to angle PQU prime , and angle PST is congruent to angle PQT prime Each of the angle pairs are corresponding angles. Therefore, corresponding angles are congruent.

perpendicular
B
reflected
C
congruent
D
parallel
