Transformations of the Plane

Identify the transformation from ABCD to A'B'C'D'.

• Translation
• Reflection across the x-axis
• Reflection across the y-axis
• 90^o counter clockwise rotation

Which of the following transformations produces a figure that is congruent to the original figure?

• Rotations

• Reflections

• Translations

• Dilations

A transformation that changes the size of a figure, but not the shape. (Hint: Not rigid motion)

• translation
• rotation
• reflection
• dilation

Translations, reflections, rotations and dilations are all known as ________________________.

• Geometry

• Transformations

• Congruent

Having the same size, shape, and measure.

• similar
• corresponding
• congruent
• equal

Determine where X' would be if you translated the figure 3 units to the left and 9 units down.

• (-4, 4)

• (-10, 2)

• (-4, -5)

• (-1, 5)

What is the function rule of a figure is Translated 9 units right and 3 units down?

• (x, y) -->

  (x - 9, y + 3)

• (x, y) -->

  (x + 9, y - 3)

• (x, y) -->

  (x + 3, y - 9)

• (x, y) -->

  (9x, 3y)

When you translate, you ___________________ a number to x and y.

• Add or subtract

• Multiply or divide

• Add or multiply

• Subtract or divide

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)

What rule describes the translation?

• (x - 6, y + 2)

• (x - 2, y + 6)

• (x + 2, y - 6)

• (x + 6, y - 2)
