Question

Use the graph to answer the question. Graph of polygon ABCD with vertices at negative 6 comma negative 2, negative 4 comma 5, 1 comma 5, negative 1 comma negative 2. A second polygon A prime B prime C prime D prime with vertices at negative 6 comma 2, negative 4 comma negative 5, 1 comma negative 5, negative 1 comma 2. Determine the line of reflection used to create the image.

Answer 1

The line of reflection used to create the image of polygon ABCD to polygon A'B'C'D' can be determined by observing the corresponding vertices of the two polygons.

Comparing the corresponding vertices, we can see that the x-coordinates remain the same while the y-coordinates change sign. This indicates a reflection across the x-axis.

Therefore, the line of reflection used to create the image is the x-axis.
