For exercises 21-23, use the following information

Parallelogram DEFG with D2,4,E5,4,F4,1,andG1,1 is rotated 270° counter clockwise about the origin.

23. Graph the pre-image and the image.

Short Answer

Expert verified

Graph of pre-image and image is

Step by step solution

01

- Meaning of pre-image

Pre-image is the parallelogram in original position

Vertices of parallelogram DEFGare D2,4,E5,4,F4,1, andG1,1

02

- Meaning of image

Image is the parallelogram D'E'F'G'which is formed after rotation.

Vertices of parallelogram D'E'F'G' are D'4,-2,E'4,-5,F'1,-4, andG'1,-1

03

- Plot both triangles

On Cartesian plane, plot the points of DEFGand join them to form a parallelogram. Then plot the points of D'E'F'G' and join them to form another parallelogram.
