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
We are given three vertices of â–ł JKL and the line of reflection y=-3. To graph the triangle, let's plot the points and then connect them.
To reflect the triangle in the line y=- 3, each vertex must be moved to the opposite side of the line of reflection while maintaining the same distance from the line. Note that point L lies on the line, so its image is itself.
Finally, we can connect the corresponding segments and obtain the image of â–ł JKL after the reflection in y=-3.
