RigidTransformations

100

Use a mapping diagram to describe the transformation.

(x,y)->(x+4,y+3)

200

Describe the transformation.

A rotation of +90^o (or -270^o) about the origin.

300

Identify the two transformations that could have been used to create the image.

1) A reflection over the x-axis.

2) A rotation of 180o about point (-3.5, 0).

400

Write the ordered pair of point A' if a rotation of +90^o took place around point k.

(-4,-1)

500

Write the ordered pair of A' after a reflection of the line y = 2x + 1.

(-3,5)

Non-RigidTransformations

100

What is the scale factor of the dilation?

1/2=0.5=50%

200

Find the center of dilation.

(-4,1)

300

Write the ordered pair of A' if the figure is dilated by a factor of 3/2 about the midpoint of CB.
