Question

ac = 4 units
what is the length of bc, the image of segment bc?
bc = units

Explanation:

Step1: Identify transformation type

The problem involves image segments (A'C, B'C) from original segments, implying a rigid transformation (preserves length).

Step2: Count vertical grid units for BC

From point C to B, the vertical distance is 4 units (matches A'C=4, confirming rigid transform).

Step3: Conclude B'C length

Rigid transformation keeps BC = B'C = 4.
