3D shapes and Transformation Review

Translate point A (-8, 6) two to the left and four down. Mark the image on the graph.

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

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 rule describes the translation?

• (x - 6, y + 2)
• (x - 2, y + 6)
• (x + 2, y - 6)
• (x + 6, y - 2)

A rigid motion ...

• preserves size and location
• preserves shape and location
• preserves size and shape
• makes the figure larger

A rigid motion creates figures that are ____________.

• congruent
• different sizes
• similar
• larger

To translate the blue shape to the pink shape, which of the following do we need to do?

• 5 Right

  2 Down

• 5 Left

  2 Up

• 3 Right

  1 Down

• 3 Left

  1 Up

Choose all of the following that will translate shape A to shape B.

• (x-5, y-3)

• (x-3, y-5)

• (x+5, y+3)

• (x+3, y+5)

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

• (5, 3)

• (3, -5)

• (-5, 3)

• (-3, 5)

Answer explanation

J is at (0,1)
Translating 5 left means decreasing x by 5.
Translating up 2 means increasing y by 2.

$\left(0-5,\ 1+2\right)\longrightarrow\ \left(-5,3\right)$
J' is at (-5, 3)
