This short check helps your tutor see where to start. Work on your own,
without a calculator. Do your best -- the goal is to find what to work
on together, not to grade you.

Triangle ABC is congruent to triangle DEF. Is triangle ABC also
similar to triangle DEF?

B

Procedures

1

Triangle ABC has AB = 3. Triangle DEF is similar to triangle ABC
(ABC ~ DEF), with corresponding side DE = 12. What is the scale
factor from ABC to DEF? Enter a number.

2

Triangle ABC ~ triangle DEF. Triangle ABC has sides AB = 2, BC =
5, AC = 4. Triangle DEF has sides DE = 6, EF = 15, DF = 12. What
is the scale factor from ABC to DEF?
