Determine whether the polygons are similar. If they are similar write a similarity statement and its scale factor.

• Not similar

• Similar. QRST ~ ZWXY; k = 2:1

• Similar. QRST ~ ZWXY; k = 8:3

• Similar. QRST ~ WXYZ; k = 2:1

Determine whether the polygons are similar. If they are similar write a similarity statement and its scale factor.

• Not similar

• Similar. ΔABC ~ ΔFDE; k = 1:1

• Similar. ΔABC ~ ΔDEF; k = 1:1

• Similar. ΔABC ~ ΔFDE; k = 6:5

• Similar. ΔABC ~ ΔDEF; k = 6:5

ABCDE ~ FGHJK

What is the scale factor of ABCDE to FGHJK?

• 1:2

• 2:1

• 2:5

• 5:2

Answer explanation

The scale factor is 1:2 because ABCDE was listed first in the similarity statement. Therefore 4 corresponds to 8.
