Identify Rigid Transformations

Front

What is a transformation that produces a mirror image of a figure?

Back

Reflection

Front

What type of transformation turns a figure about a fixed point?

Back

Rotation

Front

What do we call the original figure before a transformation?

Back

Pre-image

Front

In a reflection, what is the line called that the figure is flipped over?

Back

Line of symmetry

Front

What is the transformation that slides a figure from one position to another without changing its shape or size?

Back

Translation

Front

If a figure is reflected over the y-axis, how does the x-coordinate of each point change?

Back

The x-coordinates change sign.

Front

What is the result of a 90-degree clockwise rotation of the point (x, y)?

Back

(y, -x)

Front

What is the result of translating the point (3, 2) by 4 units to the left and 3 units up?

Back

(-1, 5)

Front

What is the transformation that enlarges or reduces a figure?

Back

Dilation

Front

If a quadrilateral is reflected over the x-axis, how does the y-coordinate of each point change?

Back

The y-coordinates change sign.
