Ch 8.8 Similarity and DilationsMaking Faces Project

(Due Monday)

Warm UpWarm UpGraph the following points to create

triangle ABC.A (1, 2) B (4, 1) C (2, 4)

Now, complete the following transformations:• Reflect across the x-axis• Translate 8 units left and 6 units down• Rotate 90º counterclockwise

Similarity Similarity and and

DilationsDilationsChapter 8.8

Similar Polygons: have the same shape, but can be different sizes

Dilation: stretches or shrinks a figure. The image created is similar to the original figure

Distortion: scales the figure in one dimension, leaving the other dimension the same

TASK #1Place a sheet of graph

paper over the face parts worksheet, and

trace the desired parts to make a face

Place letters along the width and numbers

along the length of the graph paper to provide reference coordinates

for each cell of the face.

Create the face

TASK #1

TASK #2Enlarge the face

To do this, you will double the

width and length of the cells of the

face.

You will need to copy each cell’s content form the original into the appropriate cell of the

enlargement.

(What is in cell D3 of original will go in cell D3 of enlargement, it will just be much larger)

TASK #2

TASK #2

TASK #3Distort the face

To distort the face, you will scale up one dimension, and leave the other dimension the

same. Please scale the one dimension by 3 or 4.

TASK #3

To Recap:To Recap:Task #1: Draw the face

(one box for each dimension)

Task #2: Enlarge the face(two boxes for each dimension)

Task #3: Distort the face(one box for each on one dimension, three boxes for

each on the other dimension)

When you are done, color in the faces.Note: each face should be on a separate

piece of graph paper.
