Transformations Review

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

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

What is the algebraic notation of a figure is Translated 2 units right and 5 units up?

• (x, y) --> (x - 2, y - 5)
• (x, y) --> (x + 2, y + 5)
• (x, y) --> (x + 5, y - 2)
• (x, y) --> (5x, 2y)

Which transformations keep the images congruent?

• Translation

• Reflection

• Rotation

• Dilation

What is a reflection?

• When you turn an object around a point.
• When you slide an object form one place to another.
• When you flip or mirror an object across a line.
• When you resize an object.

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

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

Reflect Point C over the y-axis:

• (-3, 2)
• (3,2)
• (-2,3)
• (3,0)

Reflect over x-axis. Which point would be at (3, -6)

• A
• B
• C
• H

A dilation is which of the following: 

• only an enlargement
• only a reduction
• Either an enlargement or a reduction
• Neither an enlargement or a reduction

When the scale factor of a dilation is less than one, the dilation is a reduction.

• True
• False

How many degrees was the figure rotated?

• 90 degrees counterclockwise 
• 180 degrees
• 90 degrees clockwise
