Name __________________ Block ___
Basic and Challenge:
hallenge: All problems
Using the SSS Theorem. Verify that ∆ABC~∆DEF.. Then find the scale factor of ∆ABC ∆DEF
1a)
∆ABC: BC = 18, AB = 15, AC=12
∆DEF: EF= 12, DE=10, DF=8
1b)
∆ABC: BC = 16, AB = 10, AC=20
∆DEF: EF= 40, DE=25, DF=50
Using the SSS Similarity Theorem
2a) Is either ∆JKL or ∆RST similar to ∆ABC?
2a) Is either ∆JKL or ∆RST similar to ∆ABC?
3a) Determine whether the triangles are similar. If they are, write a similarity statement
and find the scale factor of triangle B to Triangle A
A.

3b) Determine whether the triangles are similar. If they are, write a similarity statement
and find the scale factor of triangle B to Triangl
Triangle A.
4) Show the triangles are similar and write a similarity statement. Explain your reasoning.

Reflection and Self Assessment
1) Describe how you did: Which problems were hard and why? Which problems were easy and why? Did someone help you?
(Who?) If you had help do you feel like you could do a similar worksheet on your own now? Why or why not. If this is not on
o
time explain why. (If
If this worksheet is late your grade will be base
based solely on this reflection.)
2) What would you like us to go over more in class? What are your next steps for mastering this material and/or improving
your math skills or math grade?
