# Lesson 18 - Sequence of Transformations (Day 1)

## MODEL PROBLEM: First reflect the triangle over x = 1. Then translate the image using the rule (x-4, y+2). Move points A', B', and C' to where you think the final image will be.

## MODEL PROBLEM - Use the applet above to help you state the coordinates.

State the coordinates of the final image.

## First rotate the triangle over the 90 degrees counterclockwise about the origin. Then reflect the image using x = 1. Move points A', B', and C' to where you think the final image will be.

## Use the applet above to help you state the coordinates.

State the coordinates of the final image.

## First reflect the triangle over y = -1. Then translate the image using the rule (x+2, y+5). Move points A', B', and C' to where you think the final image will be.

## Use the applet above to help you state the coordinates.

State the coordinates of the final image.

## First reflect the triangle over y = 1. Then rotate the image 180 degrees about the origin. Move points A', B', and C' to where you think the final image will be.

## Use the applet above to help you state the coordinates.

State the coordinates of the final image.

## First reflect the triangle over the x=5 Then translate the image using the rule (x-5, y-3). Move points A', B', and C' to where you think the final image will be.

## Use the applet above to help you state the coordinates.

State the coordinates of the final image.

## CHALLENGE: First reflect the triangle over y = 2. Then translate the image using the rule (x-6, y+4). Finally, rotate the image by 90 degrees counterclockwise about the origin. Move points A', B', and C' to where you think the final image will be.

## CHALLENGE - Use the applet above to help you state the coordinates.

State the coordinates of the final image.
