Question

Which scale drawing is a dilation that decreased the size of the original object it represents? Figure 1 is the star with scale 1:5
, Figure 2 is the octagon with scale 2:0.5
, Figure 3 is the triangle with scale 10:1
, and Figure 4 is the pentagon with scale 1:0.1
.

Answer 1

Figure 1.

Reason: 1:5 gives scale factor 1/5 = 0.2 < 1, so the drawing is a reduction. The others have scale factors > 1 (2:0.5 = 4, 10:1 = 10, 1:0.1 = 10).
