Chapter 4.7, Problem 29PPS

(a)

To determine

Find the type of transformation she used to produce each flower in the design.

Answer to Problem 29PPS

Rotation or reflection.

Explanation of Solution

Given :

Tionne used the stencil.

Calculation:

Since a stencil can print the same design from both the sides .

So, T can use the stencil on one side , then reflect it (or flip) to get the print and again reflect it (flip) to bring it on the original side and print the flower.

Or , she can rotate it twice to obtain the design.

So, T can use stencil , the transformation can be rotation or reflection , to create the design.

(b)

To determine

Find the type of transformation she used to produce each flower in the design.

Answer to Problem 29PPS

Rotation

Explanation of Solution

Given :

Tionne used the stamp.

Calculation:

Since a stamp cannot print the same design from both the sides , it can only be used from one side.

So, T can only rotate the stamp twice to obtain the design.

So, T can use stamp , the transformation can be rotation , to create the design.
