9. In similar triangles the corrosponding sides are---------------and the corrosponding angles are----

Proportional
Congruent
10. Are the two triangles below similar? If so, write a similarity statement and state which similarity criteria can be used to prove it?
11. Similarity Statement: ------------:
△ABC ~ △DEF
△ABC ~ △FDE
△ABC ~ △EFD
The triangles are not similar
Criteria
AA~
SAS~
SSS~
Not applicable, the triangles are not similar.
12. Identify two similar triangles in the figure below. State the criteria that proves they are similar. Finally, determine the length of ‾AB
Similar Triangles---------
△ABC ~ △ABD
△ABC ~ △ADB
△DBC ~ △ABD
△DBC ~ △ABC
Criteria
AA~
SAS~
SSS~
AB=
6
8

The corresponding sides are proportional and the corresponding angles are congruent.

10. The question is incomplete as it does not provide the triangles to analyze.

12. Similar Triangles: △ABC ~ △ABD and △ABC ~ △ADB
Criteria: AA~
AB = 8 (since it is the corresponding side in both triangles △ABC and △ABD)
