Question

triangle bcd is dilated by a scale factor of 2 to form triangle bcd. what is the measure of side cd? 18 91.9 90.7

Explanation:

Step1: Recall dilation property

Dilation scales lengths by the scale factor. Original \( CD = 18 \).

Step2: Calculate \( C'D' \)

Multiply \( CD \) by scale factor 2: \( C'D' = 18 \times 2 \)
\( C'D' = 36 \)

Answer:

36
