Translations & Reflections

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

• (x+2, y-5)
• (x+2, y-9)
• (x-2, y-9)

Triangle ABC is going to be translated. Where would the coordinate  A' be, if the translation rule was (x,y) --> (x+3, y-2)?

• (-1,3)
• (5,3)
• (5,8)
• (3,5)

What does a translation do to an image?

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

What transformation is happening?
(x, y) ----> (x + 2, y - 3) 

• slide up 2, left 3
• slide right 2, up 3
• slide right 2, down 3
• slide left 3, right 2

∆QRS contains the points: Q(4, 2) R(5, 1) S(3,7). If the triangle is reflected across the y-axis, what will S' be?

• S'(3, 7)
• S'(-3, 7)
• S'(-3, -7)
• S'(3, 7)

The ordered pair (-3, 4) is reflected across the x-axis. What is the new ordered pair?

• (-3, -4)
• (3, 4)
• (3, -4)
• (-3, 4)

When an ordered pair is reflected across the y-axis, what changes?

• nothing
• y-value
• x-value

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

Where will A' be at, if triangle ABC is reflected by
(x,y) --> (-x,y)?

• (2,1)
• (1,-2)
• (-1,2)
