Graph a triangle (STU) and reflect it over the y-axis to create triangle S'T'U'. Describe the transformation using words. Draw a line segment from point S to the reflecting line, and
then draw a line segment from point s' to the reflecting line. What do you notice about the
two line segments you drew? Do you think you would see the same characteristic if you
drew the line segment connecting T with the reflecting line and then t' with the reflecting
line? How do you know? (10 points)

Step-by-step explanation:

The point of reflection is that the image is as far from the line of reflection as the pre-image is. Hence you expect Sy and S'y to be the same length, and they are. Similarly, you expect Ty and T'y to be the same length. (And they are.)

This characteristic of the joining segments is part of the definition of what "reflection across a line" means. The line of reflection is the perpendicular bisector of the segment joining a pre-image point with its image.
