Translations Review

What is a translation?

• Changing quadrants in the coordinate plane

• Transformation that changes the size of a figure

• Transformation that changes the color of a figure

• Transformation that changes the position of a figure

After a translation, figures are no longer congruent.

• True

• False

Describe the translation that maps point Q to Q'.

• 7 units up, 2 units right

• 3 units left, 8 units right

• 7 units right, 2 units up

• 3 units right, 8 units left

One of triangle XYZ's coordinates is (4,2) if the rule (x,y)----> (x -4, y +2) applies, what are the new coordinates?

• (-2,2)

• (0,2)

• (0,4)

• (5,9)

• Answer not listed

After a translation, figures face the same direction but have a different size and shape.

• True

• False

Describe the translation that maps point C to C'

• 8 units right and 4 units up

• 9 units right and 4 units up

• 4 units right and 8 units up

• 4 units right and 9 units up

Tell me the coordinates for point R' after a translations 5 units right and 3 units up.

• (3,0)

• (0,3)

• (1,2)

• (2,1)

Describe the rule (x,y) ----> (x - 9) , (y + 4).

• 9 units right, 4 units up

• 9 units left, 4 units right

• 9 units left, 4 units up

• 9 units left, 4 units down

Triangle XYZ has vertices at (5, -3) (3, 2) and (-3, -8).

List the vertices after a translation 5 units left.

• (-3, 0) (2, -2) (-8, -8)

• (0, -3) (-8, 1) (-8, -2)

• (5, -8) (3, -3) (-3, -13)

• (0, -3) (-2, 2) (-8, -8)

Tell the coordinates for point C after a translation of 5 units right and 5 units down.

• (3, 3)

• (7, -2)

• (3, -3)

• (7, -2)
