Translating Coordinates

Level 1: When a figure is translated down what happens?

• The x-coordinate gets smaller (subtract from x)

• The y-coordinate gets smaller (subtract from y)

• The x-coordinate gets larger (add to x)

• The y-coordinate gets larger (add to y)

Level 1: When a figure is translated to the right, what happens?

• The y-coordinate gets smaller (subtract from y)

• The y-coordinate gets larger (add to y)

• The x-coordinate gets smaller (subtract from x)

• The x-coordinate gets larger (add to x)

Level 2: 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)

Level 2: How is triangle ABC being translated to triangle A'B'C'?

• up 3, left 8

• up 9, left 4

• down 3, right 8

• down 9, right 4

Level 2: How would you translate point P to P'?

• Translate 2 units to the right and 8 units down

• Translate 3 units down and 2 units to the right

• Translate 4 units down and 4 units to the left

• Translate 8 units to the right and 2 units down

Level 2: How is trapezoid ABCD translated to trapezoid A'B'C'D'?

• Translated 5 units down and 5 units to the right

• Translated 5 units down and 1 to the right

• Translated 8 units down and 5 units to the right

• Translated 5 units down and 4 units to the right

Level 2: What is true about the image and pre-image in a translation?

• The image is larger than the pre-image

• The image is smaller than the pre-image

• The image and pre-image are congruent (or the same size)

Level 3: What rule translates the blue shape to the green shape?

• (x, y) --> (x + 5, y + 2)

• (x, y) --> (x - 5, y - 2)

• (x, y) --> (x + 5, y + 5)

• (x, y) --> (x - 5, y - 5)

Level 3: Point K (4, 2) is translated using this rule:

(x, y)----> (x + 3, y - 1)

What are the coordinates of K'?

• (6, 3)

• (7, 3)

• (7, 1)

• (5, 3)

Level 3: 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)
