Mr. E's Reflections, Rotations, Translations Quiz

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

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

Where would point J' be if you translated point 5 units to the left and 2 units up?

• (5, 3)
• (3, -5)
• (-5, 3)
• (-3, 5)

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)

• (x, y)---->

  (x - 3, y + 2)

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.

Reflect Point C over the y-axis:

• (-3, 2)

• (3,2)

• (-2,3)

Triangle GHI is reflected across the x-axis.  What are the coordinates of I'?

• (-2, 6)
• (2, 6)
• (-6, -2)
• (6, 2)

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

• x-axis

• none of the above

Reflect about the y-axis
(-2, 7)

If you were to rotate ABCD 180° about the origin, what would the coordinates of B' be?

• (0, 0)

• (-6, -5)

• (-1, 3)

• (-6, 2)

• (3,-1)
