Answer:
the second option
Step-by-step explanation:
the SSS congruence postulate would be used
Undefined as the line is parallel to y axis ie; x=3
Each corner angle of a square is 90 degrees.
This means every 90 degree rotation ( Counter clockwise) would move A to the next corner.
Since B is the corner below A, it would take a 90 degree rotation fr A to map on B.
