Rigid Transformations Introduction

Determine the translation from triangle ABC to triangle A'B'C'.

Which rule would result in a translation of 2 units left and 3 units up?

• (x, y) → (2x, 3y)

• (x, y) → (x - 2, y + 3)

• (x, y) → (-x, -y)

• (x, y) → (x + 2, y + 3)

• (x, y) → (x + 3, y -2)

Determine where Point X' would be if you translated Point x 3 units left and 9 units down.

• (-5, -4)

• (-1, -7)

• (-4, -5)

• (-1, 5)

Determine where T' would be under the translation of 3 units to the right and 6 units up.

• (5, 1)

• (2, -5)

• (-1, 1)

• (8, -2)

Find K' if the figure is reflected across the x-axis

• (4, 1)

• (-1, -4)

• (1, -4)

• (1, 4)

What is the rule for the following reflection?

• Reflection across y = 3

• Reflection across x = −3

• Reflection across x = 3

• Reflection across y = −3

Which answer shows a reflection across the y-axis?

• a

• b

• c

• d

Triangle A is rotated 90° clockwise with the origin as the center of rotation to create a new figure. Which triangle shows the new location?

• A

• B

• C

• D

What type of rotation does this represent (from red to blue)?

• 270⁰ clockwise around the origin

• 360⁰ counter clockwise around the origin

• 90⁰ counter clockwise around the origin

• 180⁰ clockwise around the origin

Describe the rotation.

• Rotation 90^o counter clockwise around the origin

• Rotation 90^o clockwise around the origin

• Rotation 270^o counter clockwise around the origin

• Rotation 180^o counter clockwise around the origin
