Transformation Geometry Non Rigid Definition Understanding

The non-rigid transformation that changes the size of the pre-image is called:

• Dilation

• Rotation

• Translation

• Reflection

Definition: The figure before a transformation has occurred. 

• Pre-image

• Image

• Translation

• Reflection

A dilation is which of the following: 

• only an enlargement

• only a reduction

• either an enlargement or a reduction

• neither an enlargement nor a reduction

Translations, reflections and rotations are all known as ________________________.

• Geometry

• Rigid Transformations

• Congruent

• Non- Rigid Transformations

How do you write the algebraic notation when the scale factor is 3?

• (x, y) goes to (1/3x, 1/3y)

• (x, y) goes to (-3x, -3y)

• (x, y) goes to (x + 3, y + 3)

• (x, y) goes to (3x, 3y)

Dilate Point B by a scale factor of 1/2

• (1.5,-4)

• (-1.5,1)

• (-1,-1.5)

• (-2,-2)

Dilate Point B by a scale factor of 3:

• (12,0)

• (12,12)

• (4,3)

• (0,12)

Which transformation is NOT a rigid motion (the size changes)?

• reflection

• rotation

• dilation

• translation

A type of transformation where a figure is “flipped” over a line of symmetry. A reflection produces a mirror image of a figure.

• rotation

• translation

• dilation

• reflection

A transformation that “turns” a figure about a fixed point at a given angle and a given direction.

• rotation

• translation

• reflection

• dilation
