6.3 Worksheet
Name __________________________________
Date ___________________
List all pairs of congruent angles for the figures. Then write the ratios of the corresponding sides in a statement of
proportionality.
1. Δ ABC ~ Δ DEF
3. PQRS ~ ZWXY
2. CDEF ~ MJKL
4. WXYZ ~ MNOP
Determine whether the polygons are similar. If they are, write a similarity statement and find the scale factor.
5.
6.
7.
The polygons are similar as indicated. Find the value of x.
8. BCDE ~ KLM
In the diagram, WXYZ  MNOP.
9. Find the scale factor of WXYZ to MNOP.
10.
Find the values of x, y, and z.
11. Find the perimeter of WXYZ.
12. Find the perimeter of MNOP.
13. Find the ratio of the perimeter of MNOP to the
perimeter of WXYZ.
Use the similarity statement to find the scale factor of the polygon on the left to the polygon on the right.
Then find the perimeter of each polygon.
14. STUV ~ XYZW
15. In the figure, ΔABC ~ ΔDEF. Find the value of the variable.
16. Kites You are flying a kite on a sunny day. The kite has the side lengths shown in the figure below at the left.
The kite’s shadow has the side lengths shown in the figure below at the right.
Is the shadow similar to the kite? Explain your reasoning.
