Transformations Congruent and Similar Figures

A type of transformation where a geometric figure slides horizontally, vertically, or both. What type of transformation is this? 

• dilation

• translation

• rotation

• reflection

Reflect Point C over the y-axis:

• (-3, 2)

• (3,2)

• (-2,3)

• (3,0)

Dilation

• Is a transformation that slides the figure up, down, left, or right.

• Is a transformations that flips the figure over a given axis.

• Is a transformation that turns or spins the figure.

• Is a transformation that enlarges or reduces the figure. It creates similar shapes.

Determine if the two figures are congruent by using transformations. If so, explain the transformation or transformations that map the first figure onto the second figure.

• congruent; a counterclockwise rotation of 90° followed by a translation

• congruent; reflection

• congruent; translation

• not congruent
