Question

answer the question correctly to continue: which of the following scale factors will make a shape smaller during dilation?

Explanation:

Step1: Recall the rule of dilation

When the scale factor \(k\) satisfies \(0 < k< 1\), the shape becomes smaller.

Step2: Analyze each option

• For \(k = 0.5\), since \(0<0.5 < 1\), the shape will be smaller.
• For \(k = 2\), since \(2>1\), the shape will be larger.
• For \(k = 1\), the shape remains the same size.
• For \(k = 3\), since \(3>1\), the shape will be larger.

Answer:

\(0.5\)
