Transformations Vocabulary Math

What is the definition of "translation"?

• A transformation that moves every point of a figure the same distance and the same direction (slide). Shape, size, and orientation are preserved.

• A transformation that flips a figure over a line of reflection. Shape and size are preserved.

• A transformation that turns a figure around a fixed point. Shape and size are preserved.

• The number of degrees the figure rotates.

Which vocabulary word matches the definition: "A change in the position, shape, or size of a figure"?

• Translation

• Transformation

• Rotation

• Enlargement

What is the definition of "reduction"?

• A dilation with a scale factor greater than 1 because the image is larger than the preimage

• A dilation with a scale factor > 0 and < 1 because the image is smaller than the preimage

• A transformation that flips a figure over a line of reflection

• The number of degrees the figure rotates

Which vocabulary word matches the definition: "Line over which a figure is reflected. Corresponding vertices of the preimage and image are the same distance from this line"?

• Line of reflection

• Center of rotation

• Scale factor

• Sequence of transformations

What is the definition of "sequence of transformations"?

• A transformation that moves every point of a figure the same distance and the same direction (slide)

• A transformation that flips a figure over a line of reflection

• Two or more rotations, reflections, translations, or dilations mapping a preimage to an image

• The number of degrees the figure rotates

Which vocabulary word matches the definition: "The original figure, before a transformation"?

• Image

• Pre-image

• Scale factor

• Reduction

What is the definition of "dilation"?

• A transformation that moves every point of a figure the same distance and the same direction (slide)

• A transformation that flips a figure over a line of reflection

• An image that has the same shape, angle measures and orientation, but proportional side lengths with its preimage

• The number of degrees the figure rotates

Which vocabulary word matches the definition: "The number of degrees the figure rotates"?

• Angle of rotation

• Center of rotation

• Scale factor

• Sequence of transformations

What is the definition of "scale factor"?

• A transformation that moves every point of a figure the same distance and the same direction (slide)

• Also known as r, is the ratio of a length in the image to the corresponding length in the preimage.

• Also known as r, is the number of degrees the figure rotates

• The original figure, before a transformation

What is the definition of "enlargement"?

• A dilation with a scale factor greater than 1 because the image is larger than the preimage

• A dilation with a scale factor > 0 and < 1 because the image is smaller than the preimage

• A transformation that flips a figure over a line of reflection

• A transformation that turns a figure around a fixed point
