Question

which transformation would take figure a to figure b?

Explanation:

Step1: Observe the orientation and position

Figure A and Figure B have the same shape and size, but Figure B is the mirror - image of Figure A across the y - axis.

Step2: Recall transformation types

A reflection across the y - axis changes the sign of the x - coordinates of all the points of a figure while keeping the y - coordinates the same. This is consistent with the change from Figure A to Figure B.

Answer:

Reflection across the y - axis.
