Question

Pentagon A'B'C'D' E' is the image of pentagon ABCDE under a dilation with a scale factor of 1 2 B What is the length of segment OD ? 4 of 4

Answer 1

The length of side CD of pentagon ABCDE is 4 units. The dilation factor is 1/2. So length of side C'D' is 1/2 half of length of CD.

Determine the length of side C'D'.

`\begin{gathered} C^(\prime)D^(\prime)=(1)/(2)\cdot4 \\ =2\text{ units} \end{gathered}`

Thus length of segment CD is 2 units.
