Question

6. Rectangle ABCD with A(0,0), B(0,4), C(5,4), and D(5,0): rotate 90° clockwise. 71 a. What is the "arrow rule" to show this transformation? 14 b. What are the vertices of the image after the transformation?

Answer 1

Arrow Rule of Transformation.

a. The arrow rule for 90 degrees clockwise rotation is

`(x,y)\rightarrow(-y,x)`

b. The vertices of the images after transformation are;

`\begin{gathered} A(0,0)\rightarrow A^I(0,0) \\ B(0,4)\rightarrow B^I(-4,0) \\ C(5,4)\rightarrow C^I(-4,5) \\ D(5,0)\rightarrow D^I(0,5) \end{gathered}`
