Question

lesson 2
describing single rigid transformations in the coordinate plane

for problems 1 - 4, write the single transformation that maps each lettered figure onto its prime - lettered image.

Explanation:

Step1: Analyze figure A transformation

Observe the position of figure A and A'. The x - coordinates of corresponding points change sign while y - coordinates remain the same. This indicates a reflection across the y - axis.

Step2: Analyze figure D transformation

Observe the position of figure D and D'. The y - coordinates of corresponding points change sign while x - coordinates remain the same. This indicates a reflection across the x - axis.

Answer:

1. Reflection across the y - axis
2. Reflection across the x - axis
