Exercise 2 Page 552

Each vertex must be moved to the opposite side of the line of reflection while maintaining the same distance from the line.

Practice makes perfect

Before we begin, let's add the given line of reflection to the graph of △ ABC.

To reflect the triangle in the line x=-3, each vertex must be moved to the opposite side of the line of reflection while maintaining the same distance from the line.

Finally, we can connect the corresponding segments and obtain the image of △ ABC after the reflection in x=-3.
