Question

which of the following transformations maps opqr onto opqr?

Explanation:

Step1: Analyze the transformation type

Observe the orientation and position change of the figure. The figure OPQR and O'P'Q'R' have opposite orientations. A rotation and a translation alone do not change the orientation of a figure. A reflection changes the orientation.

Step2: Identify the line of reflection

By comparing the corresponding points of the two figures, we can see that if we reflect the figure OPQR across the y - axis, the x - coordinates of the points will change their signs while the y - coordinates remain the same, which is consistent with the transformation from OPQR to O'P'Q'R'.

Answer:

Reflection across the y - axis.
