Summarize
Plot the ordered pairs given in the table to make six different figures. Draw each figure on a separate sheet of graph paper.
Connect the points with line segments as follows:
• For Set 1, connect the points in order. Connect the last point in the set to the first point in the set.
• For Set 2, connect the points in order. Connect the last point in the set to the first point in the set.
• For Set 3, connect the points in order. Do not connect the last point in the set to the first point in the set.
• For Set 4, make a dot at each point (do not connect the dots).
After drawing the six figures, compare Figure 1 to each of the other figures and answer the following questions.
1. How do the coordinates of each figure compare to the coordinates of Figure 1? If possible, write general rules for making
Figures 2-6.
2. Describe any similarities and/or differences between Figure 1 and each of the other figures.
• Describe how corresponding sides compare.
• Describe how corresponding angles compare.
3. What would be the effect of multiplying each of the coordinates in Figure 1 by ½?
4. Which figures are similar? Describe a sequence of transformations that takes Figure 1 to the similar figure.
5. Translate, reflect, rotate (between 0 and 90°), and dilate Figure 1 so that it lies entirely in Quadrant III on the coordinate
plane. You may perform the transformations in any order that you choose. Draw a picture of the new figure at each step and
explain the procedures you followed to get the new figure. Use coordinates to describe the transformations and give the scale
factor you used. Describe the similarities and differences between your new figures and Figure 1.

Katherine wants to enlarge her favorite picture of her family so she can hang it in her bedroom.
The picture currently has dimensions of 5 x 7. She wants to enlarge it to a
15 x 21. When she takes the photo to the photo center, the retail clerk says that Katherine
would have to write a rule for her enlargement.
What rule did Katherine write so the clerk would know how much to enlarge the picture?
What if Katherine wanted to shrink the picture to 2.5 x 3.5 (so she could keep a wallet size
picture of her family in her purse), what rule would she write to shrink her photo? What is the
number called that Katherine is using to enlarge and/or shrink the picture?

F (6, 4),
G (6, 2)
Perform the following dilations and answer the follow-up question.
1.) (2x, 2y) 2.) (1/4 x, 1/4 y)
3.) (3x, 1/3y)
4.) Are any of the figures congruent? Are any of the figures similar?

Notes
Dilations
When you are multiplying the x and the y coordinates by the same
number (or the same scale factor) then your image will be similar.
Ex. (x,y)
(x,y)
(4x, 4y)
Similar figure
(1/3x, 1/3y)
If you multiply the x and the y coordinates by a different number
(or a different scale factor) then your image will be distorted.
Ex. (x,y)
(6x, 2y)
Distorted figure
Reminder:
Whenever your scale factor is greater than 1, then you are enlarging
your image. As a result, whenever your scale factor is less than 1,
then you are shrinking your image.

Today you will cut, paste and define each of the angle relationship in
your mathematics notebook. The today's objective is to identify each
angle and REFINE your understanding of each term.
Stage 1: First forming your knowledge
Two lines that meet at a point...something with
degrees.
Example:
Angle
Stage 2: You have a better understanding but still need
more information
Two rays that meet and extend in different
directions
Stage 3: You conceptually understand the term. You are
using other vocabulary terms to explain the term.
Two rays that meet at an initial point or vertex,
extending in different directions measured in
degrees.
