Question

if segment ab is 2 centimeters long, how long is segment ab?

Explanation:

Step1: Identify Transformation Type

The figures appear to be congruent (same shape, size), so transformation is rigid (e.g., rotation/reflection).

Step2: Apply Congruence Property

In rigid transformations, corresponding segments are equal. \( AB \) and \( A'B' \) are corresponding segments.

Step3: Determine Length

Given \( AB = 2 \, \text{cm} \), so \( A'B' = AB = 2 \, \text{cm} \).

Answer:

2 centimeters
