Question

each problem shows a pair of scaled copies. answer each question.

1. what scale factor takes polygon n to polygon m?

16 in.
n
7 in.
→ 48 in.
m
21 in.

1. what scale factor polygon a to poly

56 m

1. what scale factor takes polygon j to polygon h?

6 yd.
8 yd.
j
→ 20 yd.
15 yd.
h

1. what scale fa polygon c to

27
33 cm
c

1. what scale factor takes polygon p to polygon q?

1. what sc polygon

12 km

Explanation:

Step1: Find scale factor for N→M

Divide M's side by N's side: $\frac{48}{16}=3$ or $\frac{21}{7}=3$

Step2: Find scale factor for J→H

Divide H's side by J's side: $\frac{15}{6}=2.5$ or $\frac{20}{8}=2.5$

Step3: Note incomplete problems

Problems 2,4,6 have missing polygon data, cannot solve. Problem5 has no polygon dimensions shown, cannot solve.

Answer:

1. 3
2. $\frac{5}{2}$ or 2.5
3. Cannot solve (missing target polygon data)
4. Cannot solve (missing target polygon data)
5. Cannot solve (missing polygon dimensions)
6. Cannot solve (missing target polygon data)
