Question

triangle ijk is dilated by a scale factor of 1/2 to form triangle ijk. what is the measure of side ki? answer attempt 1 out of 2

Explanation:

Step1: Recall dilation property

When a figure is dilated, the lengths of its sides are multiplied by the scale - factor.

Step2: Identify the original side length and scale - factor

The original length of side $KI = 60$, and the scale - factor $k=\frac{1}{2}$.

Step3: Calculate the new side length

The length of the dilated side $K'I'$ is given by $K'I'=k\times KI$. Substitute $k = \frac{1}{2}$ and $KI = 60$ into the formula: $K'I'=\frac{1}{2}\times60$.
$K'I' = 30$

Answer:

30
