Section 3 Review - Rigid Transformations

What is the rule that will move point T to the origin?

• (x,y) -> (x+5, y+3)

• (x,y) -> (x+2, y-2)

• (x,y) -> (x-3, y-5)

• (x,y) -> (x-5, y-3)

What will be the coordinates if R' after a reflection across the line y = -x?

• (-1, 3)

• (1, -3)

• (-3, 1)

• (-3, -1)

What will be the coordinates of R' after a 90 degree clockwise rotation around the origin?

• (-1, -3)

• (-3, 1)

• (1, 3)

• (-3, -1)

How many lines of symmetry does a decagon have that will reflect it onto itself?

• 8

• 12

• 10

• 6

A reflection across which line will carry the figure onto itself?

• x = -2

• y = x

• y = -2

• x = -1

This graph shows a reflection across what line?

• x = 1

• The y-axis

• y = 1

• The x-axis

What rotation will carry the regular nonagon onto itself? Select all that apply.

• 40 degrees around its center

• 90 degrees around its center

• 120 degrees around its center

• 360 degrees around its center

The figure on the right is the pre-image, and the figure on the left is the prime image. Write a rule for the translation.

• (x, y) -> (x + 6, y + 4)

• (x, y) -> (x - 6, y - 4)

• (x, y) -> (x + 4, y + 6)

• (x, y) -> (x - 4, y - 6)

Describe the transformation shown in the graph.

• Reflect over x-axis
• Reflect over y-axis
• Rotate 270 degrees CCW
• Rotate 90 degress CCW
