Identify Reflections and Rotations

A flip or mirror is also called a ___________.

• Translation

• Reflection

• Rotation

• Transformation

The figure is rotated counter clockwise. Describe the rotation.

• 1 full turn

• 1/2 turn

• 1/4 turn

• 3/4 turn

Which answer shows a reflection across the y-axis?

• a

• b

• c

• d

Identify the transformation from A to D. (Note: The figure was rotated counterclockwise.)

• 1 full turn

• 3/4 turn

• 1/2 turn

• 1/4 turn

What happens when a shape is transformed by a translation, reflection or rotation?

• the size and shape remain the same

• the size and shape change

• only the size changes

• only the shape changes

What order of rotational symmetry does this shape have?

• 1

• 2

• 4

• 6

This shape has

• line of symmetry only

• rotational symmetry only

• line of symmetry and rotational symmetry

Find K' if the figure is reflected across the x-axis

• (4, 1))

• (-1, -4)

• (1, -4)

• (1, 4)

State the line of reflection.

• Reflection across y-axis

• Reflection across x-axis

• Reflection across x = 1

• Reflection across y = 1

If the dotted figure is the image, the original figure was reflected over the ...

• x-axis

• y-axis
