Question

4b) explain why figure b is not the image of figure a after a reflection using line l.

Explanation:

In a reflection, corresponding points of the original figure and its image are equidistant from the line of reflection. For Figure A and B, if we consider key - points on the figures, the distances from these points to line $\ell$ are not consistent as they should be in a reflection. Also, the orientation of some parts of the figures relative to the line of reflection is incorrect for a reflection transformation.

Answer:

Corresponding points of Figure A and B are not equidistant from line $\ell$, and the orientation of parts of the figures relative to line $\ell$ is wrong for a reflection.
