John was a real big Kobe fan and wanted a large poster for his room. The original poster was 4 ft. wide and 3 ft. tall. John wanted the new

poster to be 6 ft. tall. What is wrong with John’s poster? What should he have done differently?

“Go Big or Go Home”Isabella noticed that the new

base is 9 units longer than

the original one, so she

thinks that the height of the

new triangle should be 9

units longer, or 18 units high.

Buford noticed that the new

base is 4 times longer, so he

thinks that the height of the

new triangle should be 4

times longer or 36 units high.

Isabella Buford

Reduce (make smaller) the

shape so that the base

(bottom) of the new

smaller triangle is 1 unit

long? How tall should the

triangle be to keep its

original shape? How did you

figure this out? Draw the

new shape on your graph

paper.

a. Draw a rectangle that measures 5 units by 3 units. Enlarge it

so that each side is four times as long as the original.

“Shapes Galore”

b. Draw a right triangle with a base of 2 units and a height of 4

units. Make three “copies” so that the lengths of the new sides

are:

“Shapes Galore”

“Left, Right, Up & Down”

a.Plot the following ordered

pairs and connect them:

(-2,-4); (-2, 4); (2, 4); (2, -4).

• What shape did the

make?


b. What is the length of each of the sides of the shape that you made?


c. Draw a figure that is enlarged by a factor of 1.5 and still has one corner (or vertex) at (-2, -4). What are the coordinates of the corners (or vertices) for the new shape? What are the lengths of the sides now?


d. Now draw a figure that is half the size of the original, again with one vertex still at (-2, -4). What are the coordinates of the vertices of the reduced shape? What are its side lengths?

Work with your team to describe how you can tell if an image has been enlarged correctly. When you have come to an agreement, write your ideas as a Learning Log entry. Title this entry “Enlarging Figures” and label it with today’s date.

The Old School TV Co. currently makes television sets using the old ratio of (4w : 3t). They

want to increase the size of their current model, which is 12” wide and 9”tall, to make a selection of wider television sets. Create a list of options that the Old School TV Co. could use when making new television sets.
