To identify: The type of congruence transformation.
Answer to Problem 47SR
The transformation is a reflection.
Explanation of Solution
Translation is one of the congruence transformations
Rotation is one of the congruence transformations that have a center point along object through which whole figure rotate. And the point of image that rotate along center form a rotation
A reflection is transform in a line. Reflection in a line is a function that maps a point to its image. This can be also represented as that if the point on the line then the point's image and original point are on the same point. If the point is away from the line that means the point is not on the line then the line is the perpendicular bisector of the segment joining the two points.
Refer the given figure.
The blue colour parallelogram is a reflection of the green coloured parallelogram about the y axis.
Therefore, the transformation is a reflection.
