Answer:
8) ΔCAB ~ ΔFDE; SSS
9) ΔMNQ ~ ΔPNO; SAS
10) ΔDBE ~ ΔABC; SAS
Step-by-step explanation:
8) The side ratios, shortest to longest, are ...
6 : 8 : 10 = 9 : 12 : 15 = 3 : 4 : 5
so are the same for both triangles. Triangles CAB and FDE are similar by SSS.
__
9) MN/NQ = PN/NO = 6/5 = 12/10. The vertical angles between these corresponding sides are congruent. Triangles MNQ and PNO are similar by SAS.
__
10) BD/BA = BE/BC = 21/28 = 24/32 = 3/4. The shared angle between the corresponding sides is congruent to itself. Triangles DBE and ABC are similar by SAS.
