Graph a triangle (STU) and reflect it over the y-axis to create triangle STU'. 1. Describe the transformation using words. Make sure you refer to the characteristics and the coordinates.
2. 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 notice the same characteristics if you drew the
line segment connecting T with the reflecting line and then t' with the reflecting line? How do you know?

The answer to number one would be it is a reflection across the y-axis. The coordinates for triangle STU are the same as those of S'T'U' but just on the other side of the y-axis. The lines are going to be the same distance from the reflecting line for both triangles because they are still the same triangle just on different sides of the y-axis.

Step-by-step explanation:

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.
