Unit 6: Transformations: Translations and Reflections

Congruent geometric figures have the:

• Same size
• Sides Equal
• Same Size and Same Shape
• Angles Equal

What does a translation do to a figure on the coordinate plane?

• Rotates it
• Flips it
• Shrinks it
• Slides it

Write the rule for this translation:
Slide 3 up and 2 right

• (x, y)---->(x + 3, y + 2)
• (x, y)-----> (x+2, y + 3)
• (x, y)----> (x - 2, y + 3)

What transformation is happening to the red triangle to get to the blue triangle?

• Translation
• Rotation
• Reflection
• Dilation

How is triangle ABC being translated to triangle A'B'C'?

•  left 8, up 3
• left 4, up 9
• right 8, down 3
• right 4, down 9

Flipping a figure is a ...

• Rotation
• Reflection
• Dilation
• Translation

Reflections over the x-axis change the ____-__________. 

• y-coordinate
• x-coordinate

Is the picture being reflected over the y-axis or x-axis?

• y-axis
• x-axis

Reflect Point C over the y-axis:

• (-3, 2)
• (3,2)
• (-2,3)
• (3,0)

State the line of reflection.

• Reflection across y-axis
• Reflection across x-axis
• Reflection across x = 1
• Reflection across y = 1
