key idea

In a

translation,

every point in a figure moves the same distance and direction.

In a reflection across a line, every point in a figure moves to a point directly on the opposite side of the line. The new point and the original point are the same distance from the line.

In a

rotation,

every point in a figure moves the same angle and direction around a fixed point (or center of rotation).

solution

To determine which transformation maps

onto

look at each pair of corresponding points.

Notice the points in

read clockwise around the figure, but the corresponding points in

read counterclockwise around the figure.

This suggests a reflection maps

onto

It can be helpful to draw a segment from each point in

to its corresponding point in

Notice each point in

is the same distance from the

-axis

as the corresponding point in

So, a reflection across the

-axis

maps

onto
