Transformations Geometry Vocabulary

A turn is also called a ___________.

• Translation

• Reflection

• Rotation

• Transformation

What is the scale factor?

• the number used to divide dimensions of a figure

• the number used to multiply dimensions of a figure

• the number used to subtract dimensions of a figure

• the number used to add dimensions of a figure

Translation are always _______

• Congruent

• Bigger

• Smaller

• Rotated

When you reflect a shape, you ______ over an axis or line.

• Flip

• Rotate

• Slide

• Expand

The original figure prior to a transformation.

• Pre-image

• Image

The point that is to be transformed is called the:

• Pre-Image

• Image

• Post-Image

• Transformation

A dilation with a scale factor of 1/3 is a reduction. 

• True 

• False

Which transformation changes the orientation of the shape?

• Translation

• Reflection

• Rotation

• Dilation

What two transformations could be happening in this picture? Select all that apply.

• reflection and translation

• rotation and translation

• reflection and rotation

Answer explanation

The figure must be either rotated 180 degrees OR reflected across the y-axis to be oriented the way it is.

Then, a translation would slide the figure into its current position.

Translations, rotations, and reflections are three different types of what?

• Transformations

• Geometry

• Vectors

• Shapes

Answer explanation

They are all types of transformations because they transform a figure (position and orientation) on a coordinate plane.
