Question

Graph a triangle (STU) and reflect it over the y-axis to create triangle S'T'U'.
Part 1: Describe the transformation using words.

Answer 1

Part 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?
Part 3: 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?

Answer 6

Suppose you have coordinates to graph STU with. I'm using (3, 2) (6, 2) and (5, 5) I graphed that to create triangle STU.. so now, it says to reflect it across the y axis, so just draw the same triangle as close as you can on the other side of the axis. It has to be correct coordinate-wise, so make sure you line it up right. In your head, flip the triangle on the right side over to the left side of the graph, and to be right it would need to start 3 spaces to the left, at -3 to match with the one on the right that starts at 3. Then, since you've just reflected the previous image STU, label the newly reflected image as S'T'U' and you have your new triangle.

Excuse the mess of my graph, I know it sucks :p
Hopefully you can make out the points on the graph, anyways I hope this can help for the first part.
