Similarity Transformation

If a figure is dilated by a factor of 0.3, what are the new coordinates of the point (10, 5) in the image?

• (3, 1.5)

• (7, 3.5)

• (12, 6)

• (5, 2.5)

What are the coordinates of the image of a figure after it is dilated by a factor of 1.5 and then reflected over the y-axis if the pre-image has the coordinates (6, 8)?

• (-9, 12)

• (9, -8)

• (4, 12)

• (-6, 8)

Determine whether the triangles are similar.

• Yes, they are similar by SSS

• Yes they are similar by AA

• Yes, they are similar by SAS

• No, they cannot be proven to be similar

What is the result of dilating a rectangle with vertices at (0, 0), (4, 0), (4, 2), and (0, 2) by a factor of 0.5 and then rotating it 90 degrees counterclockwise?

• A rectangle with vertices at (0, 0), (0, 2), (-1, 2), and (-1, 0)

• A rectangle with vertices at (0, 0), (1, 0), (-1, 2), and (0, 2)

• A square with vertices at (0, 0), (2, 0), (2, 2), and (0, 2)

• A rectangle with vertices at (0, 0), (3, 0), (3, 1), and (0, 1)

Which of the following describes the sequence of transformations shown?

• Reflect across the x-axis and then rotate -90 degrees around the origin

• Rotate -90 degrees around the origin and then translate down.

• Reflect across the x-axis and then reflect across the y-axis.

• Translate up and then rotate 90 degrees about the origin.

What is the sequence of transformations for the image given?

Name the series of transformations that maps ABC onto DEF.

• reflect over x-axis then translate left 6 up 1

• reflect over y-axis then translate down 6 left 1

• translate right 6 down 1, then reflect over x-axis
