Reflection and Translation

What does a translation do to an image?

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

Identify the transformation FROM  Δ ABC
TO  Δ A'B'C'.

• right 8 up 4
• left 4 down 4
• right 4 up 4

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

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

Determine where T' would be if you translated T 3 units to the right and 6 units up.

• (5, 1)
• (2, -5)
• (-1, 1)
• (8, -2)

Where would A' be if you translated A 3 units to the right and 4 units down?

• (-4, 4)
• (-1, 0)
• (0, -1)

Identify the transformation.
