Geometry: Rigid Transformations Flashcard

Front

What direction is the x-axis?

Back

horizontal

Front

A type of transformation where a figure is 'flipped' over a line of symmetry. It produces a mirror image of a figure.

Back

reflection

Front

Reflect the point (2, -4) over the y-axis.

Back

(-2, -4)

Front

Identify the rule after a 180° CLOCKWISE or COUNTER CLOCKWISE: (x, y) ---> ___________

Back

(-x, -y)

Front

The result of a transformation.

Front

What is a transformation that slides a figure without changing its shape or size?

Back

translation

Front

What is the term for a transformation that turns a figure around a fixed point?

Back

rotation

Front

What is the line called that a figure is reflected over?

Back

line of symmetry

Front

If a point (x, y) is reflected over the x-axis, what is the new point?

Back

(x, -y)

Front

What is the effect of a dilation transformation on a figure?

Back

It changes the size of the figure but not its shape.
