Transformations2

Determine how to translate triangle ABC to triangle A'B'C'.

• right two, down five
• right two, down 9
• left two, up 9
• left two, down 5

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

• (-4, 4)
• (-10, 2)
• (-4, -5)
• (-1, 5)

What does a translation do to an image?

• Turns it 90* clockwise
• Mirrors it
• Shrinks it
• Slides it

Which answer shows a reflection across the y-axis?

• a
• b
• c
• d

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

• y-coordinate
• x-coordinate
• y-axis
• x-axis 

Reflecting over the y-axis changes the sign of the ____-_____________. 

• x-axis
• x-coordinate
• y-coordinate
• none of the above

A type of transformation where a figure is “flipped” over a line of symmetry. A reflection produces a mirror image of a figure.

• rotation
• translation
• dilation
• reflection

Point (-5,2) is reflected over the y axis.  Where is the new point located?

• (5,2)
• (-5,-2)
• (-5,2)
• (5,-2)

Identify the transformation from ABCD to A'B'C'D'.

• Translation
• Reflection across the x-axis
• Reflection across the y-axis
