Begin by drawing the preimage. Locate the image of each vertex so that the reflection line is the perpendicular bisector of the segment between the vertex and its image.
J'(1,6), A'(3,5), G'(2,9)
To graph a reflection image in a line, we need to follow a few steps.
We will begin by plotting the given vertices and graphing the figure. Since the given reflection is R_(y =5), we will identify y = 5 as the line of reflection.
Now we will locate the image of each vertex so that y = 5 is the perpendicular bisector of the segment between the vertex and its image. The distance between the image vertex and y = 5 must be the same as the distance between the preimage vertex and y = 5. This is shown for vertex J below.
Point A lies on the line of reflection. Therefore, the image of A is itself.
Finally, we can connect the new vertices to draw the reflection image of the given figure.
