Answer:
A) 12/8, 15/10, and 9/6
or 3/2, 3/2, and 3/2
B) PQR = PQ'R' or PQR is congruent with PQ'R'
C) You can tell the corresponding angles of PQR and PQ'R' are congruent because they have the same angle degree and have a proportionate ratio.
Step-by-step explanation:
A) PQ' = 12 and PQ = 8, Q'R" = 15 and QR = 10, PR' = 9 and PR = 6
GCF (12, 8) = 4, GCF (15, 10) = 5, GCF (9, 6) = 3
